Chapter 29

The Transformative Power of NDEs

A. The Critic’s Argument: Transformation Doesn’t Prove Anything

Imagine you survived a terrible car accident. You walked away from crumpled metal and shattered glass, and afterward you looked at life differently. You hugged your kids a little tighter. You stopped worrying so much about the small stuff. You told the people you loved that you loved them. Nobody would be surprised. Close brushes with death change people. That’s just how human beings work.

Now imagine that during the accident, you had a near-death experience—you felt yourself leave your body, you entered a brilliant light, you encountered a being of indescribable love, you watched a panoramic review of your life, and then you were sent back. Afterward, you weren’t just a little more grateful. You were profoundly, radically, permanently different. Your fear of death vanished. Your interest in material possessions evaporated. You became more compassionate, more empathetic, more patient. You developed a deep certainty that life continues beyond death and that love is the most important thing in the universe.

The skeptics look at that transformation and say: Interesting, but it doesn’t prove the experience was real.

They have a point. And in this chapter, I want to give that point a fair hearing before showing why it ultimately falls short.

Michael Marsh acknowledges that near-death experiences produce real change. In his introduction, he writes that “most subjects are changed by their experience(s), becoming more tolerant towards society, people and family.”¹ He devotes his twelfth chapter to what he calls “post-experiential outcomes,” and the very title of his second section in that chapter reveals his interest: “NDE Outcomes: The Exaltation of Personhood.”² He takes the transformation seriously. He sees something real happening in these people’s lives.

But Marsh is also careful to argue that this transformation does not prove the experience was what it appeared to be. He notes that behavioral changes after crisis events are surprisingly common. Survivors of suicide attempts from the Golden Gate Bridge have emerged as “wholly ‘different’ people,” finding “renewed vigour, outlook, insights and hope in their futures.”³ He points out that the neurophysiological mechanisms behind these sudden personality shifts after various kinds of crises are “currently poorly understood” but “very common, disparate, but widely recognized.”⁴ His argument is straightforward: if people can be radically transformed by all sorts of crisis events—car accidents, combat, suicide attempts, near-drownings—then the fact that NDEs produce transformation does not, by itself, tell us anything special about what NDEs are.

Marsh also complains that NDE researchers have handled the post-experiential dimension carelessly. He acknowledges that the topic has been “poorly researched and evaluated” by many NDE authors,⁵ and he criticizes Ring and Grey specifically for building wildly speculative theories about “cosmic consciousness” and “universal spirituality” on top of data that cannot bear such weight.⁶ He argues that what NDE authors have called evidence of spiritual transformation is really just what happens when human beings go through any kind of shattering personal crisis.

Fischer and Mitchell-Yellin take the argument further in their tenth chapter, “Near-Death Experiences, Transformation, and the Afterlife.” They begin by acknowledging the data. They cite van Lommel’s longitudinal study in which cardiac arrest survivors who had NDEs showed significantly more transformation than a control group of cardiac arrest survivors who did not have NDEs. They acknowledge that, after two years, NDE experiencers showed a significant increase in belief in an afterlife and a decrease in fear of death.⁷ After eight years, these positive changes were even more apparent.⁸

Having acknowledged all of this, Fischer and Mitchell-Yellin then make three moves to neutralize its evidential force.

First, they argue that transformation does not require supernaturalism. They draw an analogy to viewing the Grand Canyon. Standing on the rim of that enormous chasm can change a person’s perspective on life. It makes you feel small. It fills you with awe. It can make you treat people better. And yet nobody thinks the Grand Canyon is supernatural. “Supernaturalism has no monopoly on transformative power,” they write.⁹

Second, they point to psychedelic drugs. They note that ingesting substances like LSD and psilocybin can produce profound, lasting positive changes in personality—changes that closely mirror those reported by NDE experiencers. Since psychedelic experiences are caused by a physical substance interacting with the brain, they argue, the NDE transformation may be similarly physical in origin.¹⁰

Third, they make a philosophical move that is perhaps the most important. Even if a physical explanation of NDEs would rob the experience of its transformative power, they argue, that is “simply beside the point when it comes to explaining what is happening.” The aim of explanation, they say, “is to arrive at a true and accurate understanding of given phenomena. If the truth sets us free, all the better. If not, then we should seek other ways of becoming better people.”¹¹ In short: truth matters more than transformation. If NDEs are just brain chemistry, we should accept that and find other ways to improve ourselves, rather than clinging to a supernatural explanation just because it produces nice results.

Finally, they offer an intriguing speculation. The out-of-body component of the NDE, they suggest, might produce moral transformation by giving the experiencer a kind of detachment from their own narrow perspective—a step toward “putting oneself in another’s shoes.” This broader perspective does not require belief in supernaturalism; it requires only a change in viewpoint. Oliver Sacks, the famous neurologist who died of cancer, described viewing his own life “from a great altitude” after receiving his terminal diagnosis—and he was an ardent physicalist to the end.¹²

So the skeptical case on transformation boils down to this: Yes, NDEs change people. But lots of things change people. Transformation does not prove the experience was real, and a physical explanation of NDEs need not undermine the possibility of moral improvement.

B. Identifying the Weaknesses

The critics make some fair points here. I want to say that plainly. Transformation alone does not prove that an experience was objectively real. I agree with that. A person could have a vivid dream that changed their life. A person could misinterpret a hallucination as a divine encounter and emerge a better person. The transformation is real either way. So if transformation were the only evidence we had for NDEs, the skeptics would be right to dismiss it.

But that is not the situation we are in. And the critics, while making some valid observations, make several moves that do not hold up under close examination.

Start with Fischer and Mitchell-Yellin’s Grand Canyon analogy. It sounds compelling at first, but it falls apart quickly. Standing on the rim of the Grand Canyon is a normal experience. You are conscious. Your brain is functioning normally. You are perceiving something real—the canyon is actually there. The experience changes you because you encountered something true and beautiful. Nobody is surprised that encountering real beauty transforms real people.

Now compare that to an NDE occurring during cardiac arrest. The skeptics’ own position is that the brain is severely compromised—malfunctioning, oxygen-deprived, flooded with chemicals. On their view, the NDE is not an encounter with anything real. It is a hallucination produced by a dying brain. And yet this hallucination, this product of a malfunctioning organ, produces transformation that is deeper, more consistent, and more long-lasting than what most people experience from any normal event in their lives? That is a remarkable hallucination indeed. The Grand Canyon analogy actually makes the skeptics’ job harder, not easier, because it reminds us that we expect profound transformation to come from encounters with reality—not from the random misfiring of oxygen-starved neurons.

The psychedelic comparison has similar problems. Fischer and Mitchell-Yellin are correct that psilocybin and LSD can produce lasting positive changes. But this comparison is a double-edged sword. Researchers studying psychedelic experiences have noticed striking overlaps with NDEs: the sense of transcendence, the feeling of encountering ultimate reality, the dissolution of the ego, the conviction that love is fundamental.¹³ Many psychedelic researchers, far from being committed materialists, have come to suspect that these substances may open the brain to dimensions of reality it normally filters out—which is precisely what the filter/transmission model of consciousness suggests.¹⁴ The fact that psychedelic and NDE transformations look so similar may point not to the illusory nature of both, but to the real nature of what both are encountering.

Then there is the matter of what Marsh concedes and what he fails to see. He acknowledges that post-NDE transformation is real, and he rightly criticizes some NDE authors for building speculative superstructures on top of the data. Fair enough. But then he dismisses the evidential significance of the transformation by comparing it to personality changes after other crisis events. He mentions Golden Gate Bridge survivors and people who are changed by surgeries or military combat.¹⁵ What he does not do—and this is the critical weakness—is actually compare the data. He asserts the comparison without demonstrating it. Are Golden Gate Bridge survivors really transformed in the same specific ways as NDE experiencers? Do they report the same distinctive cluster of changes—loss of fear of death, increased belief in an afterlife, decreased materialism, enhanced compassion, thirst for knowledge? Marsh does not show this. He gestures at a similarity without establishing it.

And his own admission that the post-experiential dimension has been “poorly researched and evaluated” cuts both ways. If NDE researchers have not done enough rigorous study of the aftereffects, then neither has Marsh. He cannot claim that NDE transformation is nothing special while simultaneously admitting that the data has not been adequately collected. You cannot dismiss evidence you haven’t fully examined.

C. The Pro-NDE Response: Why the Transformation Matters

Let me be clear about what I am not arguing. I am not arguing that transformation proves NDEs are veridical. I said that already, and I mean it. If transformation were the only card we held, I would not be writing this book.

But transformation is not the only card we hold. It is one strand in a cumulative case that includes veridical perception (Chapter 4), blind NDEs (Chapter 7), children’s NDEs (Chapter 8), cross-cultural consistency (Chapter 20), deathbed visions (Chapter 23), shared death experiences (Chapter 24), terminal lucidity (Chapter 25), the failure of every neurological explanation (Chapters 10–17), and the philosophical problems with physicalism (Chapter 16). When you add the transformative evidence to all of that, the cumulative case gets stronger. Much stronger.

So what does the transformative evidence actually show? Let’s look at the research carefully.

The Landmark Studies

The most important study of NDE aftereffects is Pim van Lommel’s prospective longitudinal study, published in The Lancet in 2001.¹⁶ Van Lommel and his team interviewed 344 cardiac arrest survivors at ten Dutch hospitals. Sixty-two of these patients—about 18%—reported NDEs. The researchers then followed up with the patients at two years and again at eight years after their cardiac arrests.

The results were striking. At the two-year mark, NDE experiencers showed a significant increase in belief in an afterlife and a significant decrease in fear of death compared to the control group of cardiac arrest survivors who did not have NDEs.¹⁷ But here is what makes this study so powerful: at the eight-year follow-up, the changes were even more pronounced. The NDE experiencers had become more emotionally open, more empathetic, and showed increased intuitive sensitivity. Most showed no fear of death and strongly believed in an afterlife.¹⁸

Think about that for a moment. Eight years later, the transformation had not faded. It had deepened. That is not what we expect from hallucinations. Hallucinations fade. Dreams fade. Even powerful emotional experiences fade with time. But NDE transformation does the opposite. It grows.

Kenneth Ring’s earlier research found similar patterns. Ring compared NDE experiencers with people who came close to death but did not recall any NDE. Both groups showed some life changes—you would expect that from anyone who nearly died. But the NDE experiencers consistently showed more change in specific areas: greater appreciation of life, a renewed sense of purpose, increased empathy for others, and a conviction of being a stronger person.¹⁹

Michael Sabom’s research confirmed these findings with cardiac arrest patients specifically. Sabom performed statistical analysis comparing experiencers and non-experiencers on fear of death and belief in an afterlife. His findings were in complete agreement with Ring’s: NDE experiencers showed significantly greater changes in both measures. And these changes persisted across time.²⁰

But perhaps the most rigorous study of all was conducted in 1998 by clinical psychologists Gary Groth-Marnat and Roger Summers. They compared fifty-three NDE experiencers with a control group of twenty-seven individuals who had faced similar life-threatening situations but without reporting an NDE. The results were unmistakable. NDE experiencers became more concerned with the welfare of others, felt less anxiety about death, held a stronger belief in an afterlife, had more transcendent experiences, became less materialistic, and felt an increased sense of self-worth, greater appreciation for nature, and heightened awareness of paranormal phenomena. In every single measure, the changes among NDE experiencers were “consistently and significantly greater” than among those who had merely encountered life-threatening situations.²¹

Here is the finding that should give every skeptic pause. The researchers discovered that those who reported deeper NDEs—experiences with more features and greater intensity—showed more extensive changes than those who reported shallower experiences. The researchers were unequivocal about what this means: “It is the actual NDE itself, rather than some other factor such as merely being exposed to a life-threatening situation, that is crucial in facilitating change.”²²

That finding is devastating for the skeptical position. Marsh wants to say that NDEs produce the same kind of transformation as any crisis event. But the Groth-Marnat and Summers study directly refutes that claim. It is not the brush with death that produces the distinctive NDE transformation. It is the NDE itself.

The Distinctive Signature of NDE Transformation

One of the things that makes NDE transformation so remarkable is its distinctiveness. These are not generic “I’m grateful to be alive” changes. Chris Carter, in his thorough survey of the aftereffects literature, identifies a specific cluster of changes that consistently appear across studies, across cultures, and across decades. They include: a thirst for knowledge; increased compassion and tolerance for others; reduced competitiveness; reduced interest in material possessions; an increased interest in spirituality coupled with a decreased interest in sectarian religion; a greater appreciation for life coupled with a greatly reduced fear of death; and most strikingly, a greatly increased belief in an afterlife.²³

Notice the pattern. These changes are not random. They are not the sort of thing you would predict from a malfunctioning brain producing garbled signals. They form a coherent picture: a person who has encountered a reality of overwhelming love, who has experienced the continuation of consciousness beyond the body, and who has come back with the deep conviction that the material world is not all there is. The transformation makes perfect sense if the experience was real. It makes very little sense if it was a hallucination.

Compare this to what hallucinations actually produce. People who experience hallucinations—from fever, drugs, psychosis, or sensory deprivation—do not typically report a consistent cluster of lasting positive life changes. Hallucinations can be vivid. They can be terrifying. They can be beautiful. But they do not routinely transform people in the specific, enduring ways that NDEs do.²⁴

Fischer and Mitchell-Yellin acknowledge this indirectly when they cite the case of Virginia Hamilton Adair, a woman who experienced profound hallucinations due to Charles Bonnet syndrome. They note that her hallucinations were deeply moving and inspiring. But then they make an odd move: they use her case to argue that transformation does not require accuracy, that inspiring hallucinations can change people too.²⁵ What they do not do is show that Adair’s hallucinations produced the same specific cluster of changes that NDEs produce. Being “deeply moved” by a hallucination is not the same thing as losing your fear of death, restructuring your values, and sustaining those changes for decades.

The Transformation That Hallucinations Cannot Produce

Let me press this point further, because it is important. The skeptics need hallucinations to do an enormous amount of work in their theory. They need hallucinations to explain not just the vivid imagery of NDEs, not just the tunnel and the light and the being of love, but also the specific, measurable, enduring life changes that follow. And hallucinations simply cannot bear that weight.

Consider what we know about hallucinations from other medical contexts. Patients in intensive care units frequently experience ICU psychosis—a condition marked by vivid, often terrifying hallucinations caused by sleep deprivation, medication, infection, and the disorienting environment of the ICU itself. These hallucinations can be extremely realistic. Patients may believe they are being tortured, that spiders are crawling on the walls, or that staff members are trying to kill them. The experiences feel absolutely real to the patient in the moment.⁴⁷

But ICU psychosis does not produce NDE-type transformation. It produces trauma. Patients who experience ICU psychosis are more likely to suffer from post-traumatic stress disorder, depression, and anxiety in the months and years that follow. They do not emerge with reduced fear of death, increased compassion, and a restructured value system. They emerge frightened, confused, and often psychologically damaged.⁴⁸

Jeffrey Long makes an important observation about this. Experiences involving unexpected alterations of consciousness that are not NDEs—including ICU psychosis, illicit drug experiences, and anesthesia awareness—are much more likely to be frightening than NDEs.⁴⁹ This distinction matters. If NDEs were simply another species of hallucination, we would expect them to produce the same spectrum of psychological outcomes that other hallucinations produce. Instead, NDEs produce a completely different outcome profile. The skeptics have no good explanation for why one type of “hallucination” consistently produces lasting positive transformation while other types of hallucination consistently produce psychological damage.

Or consider anesthesia awareness, another context in which patients have unexpected conscious experiences during medical procedures. Patients who are inadvertently aware during surgery—who hear the surgeons talking, feel pressure, or even feel pain—are almost universally traumatized by the experience. They suffer nightmares, flashbacks, and severe anxiety. These experiences, like NDEs, occur in a medical context. They involve unexpected consciousness during a time when the patient should be unconscious. But they produce the exact opposite of NDE transformation.⁵⁰

The contrast is stark. If consciousness during a medical emergency is simply the brain producing random experiences, we would expect a random distribution of outcomes—some positive, some negative, some neutral. What we actually find is that NDEs produce a highly specific and overwhelmingly positive pattern of transformation, while other forms of unexpected medical consciousness produce trauma. Something different is happening in NDEs. Something that the hallucination model cannot account for.

The Depth-Transformation Correlation

I mentioned the Groth-Marnat and Summers finding earlier, but it deserves more attention because it is one of the most evidentially significant findings in the entire aftereffects literature. They found that the depth of the NDE—how many features it contained and how intense it was—predicted the depth of the subsequent transformation.⁵¹

Why does this matter? Because it creates a serious problem for the “generic crisis response” explanation. If the transformation were simply a psychological response to the shock of nearly dying, then the depth of the NDE should not matter. What should matter is the severity of the medical crisis. A patient who was clinically dead for ten minutes should be more transformed than a patient who was dead for two minutes—because the former came closer to death. But that is not what the studies show. What they show is that the experiential content of the NDE matters more than the medical severity. A patient who had a deep NDE with a life review, a tunnel, an encounter with light, and a meeting with deceased relatives is more transformed than a patient who simply felt a vague sense of peace—even if the medical crisis was equally severe in both cases.

This finding is exactly what we would expect if NDEs are genuine encounters with reality. The more you see, the more you are changed. A tourist who spends an hour in Paris is less transformed than one who spends a month. A student who reads one chapter of a life-changing book is less transformed than one who reads the whole thing. If NDE experiencers are genuinely encountering a transcendent reality, then it makes perfect sense that deeper encounters produce deeper changes. But on the hallucination model, there is no good reason why more elaborate brain malfunctions should produce more elaborate positive outcomes. Brain malfunctions do not get better when they get more severe.

Van Lommel makes a similar observation. In his study, not all cardiac arrest patients had NDEs. Only about 18% did. And not all NDEs were equally deep. Some patients had only a sense of peace or an out-of-body experience. Others had the full pattern—tunnel, light, life review, encounter with deceased relatives, border or point of no return. Van Lommel found that the patients with deeper NDEs showed the most dramatic transformation. This is consistent with what we would expect if the NDE is a genuine experience of increasing depth, not a random neural event.⁵²

Why the Transformation Deepens Over Time

One of the most remarkable features of NDE transformation is that it does not fade. It intensifies. Van Lommel’s eight-year follow-up showed that positive changes were more apparent at eight years than they had been at two.²⁶ This is not normal for any kind of psychological event. Memories of traumatic experiences typically fade or are reprocessed over time. Emotional reactions to crisis events generally diminish. The “new perspective on life” that comes from surviving a car accident or a serious illness tends to erode as ordinary life reasserts itself. We all know people who emerged from a health scare swearing they would change everything—and six months later, they were right back to their old habits.

NDE transformation does not follow that pattern. It grows. It deepens. The experiencer does not simply remember the event with less emotional intensity over time; they integrate it more fully into their identity. They become more of what the experience pointed them toward, not less.²⁷

Why? If the NDE is just a hallucination caused by a dying brain, why would its effects intensify rather than diminish? Hallucinations from anesthesia, drugs, or fever do not typically produce changes that grow stronger eight years later. But if the NDE was an encounter with something real—if the experiencer genuinely touched a deeper reality and then returned to ordinary life—then the intensifying transformation makes perfect sense. The experience was so overwhelmingly real, so far beyond anything the person had ever known, that it takes years to fully process it. The deeper you were in, the longer it takes to unpack what you encountered. That is exactly the pattern the studies reveal.

What the Transformation Looks Like in the ICU

Dr. Laurin Bellg is a board-certified critical care physician who has spent nearly two decades at the bedside of critically ill and dying patients. In her book Near Death in the ICU, she offers a perspective that Marsh and Fischer and Mitchell-Yellin never engage: what NDE transformation looks like from the clinical trenches.²⁸

Bellg describes patient after patient who, upon regaining consciousness, reported experiences that changed them permanently. What strikes her as a physician is not just that these patients are changed, but how they are changed. They do not emerge confused, disoriented, or frightened—which is what you would expect if their brains had just undergone a massive malfunction. They emerge with clarity. With peace. With a sense of purpose that they did not have before.

Bellg also documents something deeply troubling. Her research, conducted with NDE scholar Janice Holden, found that when NDE experiencers tried to share their experiences with medical staff and family members, they were frequently met with skepticism and dismissal. Even more disturbing, the deeper and more intense the NDE, the more likely the experiencer was to encounter a harmful response when trying to discuss it.²⁹ And this pattern did not improve over the decades. Experiencers from the 1930s to the 2000s were equally likely to report being dismissed or shamed when sharing their stories.³⁰

This matters enormously for the transformation argument. If NDE experiencers were seeking attention or embellishing their stories for social status, you would expect them to enjoy talking about their experiences. But the opposite is true. They share their stories reluctantly, often fearing ridicule. They persist in their transformed lives not because of social reinforcement but despite social resistance. That is the behavior of people who have encountered something real, not people who have been tricked by their own brains.

Bellg makes a powerful case that the medical profession needs to take NDE transformation seriously—not because it proves the supernatural, but because patients are being harmed by our failure to listen. She describes the bedside of a dying physician—“Dr. John,” as she calls him—who had his own NDE years earlier but never felt safe enough to talk about it with his patients or his family.³¹ His tragedy was not that his experience was dismissed as a hallucination. His tragedy was that the medical culture gave him no space to honor what had happened to him. The transformation was real. The silence surrounding it was also real.

Frightening NDEs and Transformation

Here is something the critics rarely discuss. Even frightening NDEs produce profound transformation. Jeffrey Long’s research on hellish and terrifying NDEs found that many experiencers of frightening NDEs came to view the experience as a gift—and sometimes as the most important event of their lives. The aftereffects were similar to those of pleasant NDEs: a greatly reduced fear of death, substantial positive life changes, and a renewed commitment to living well.³²

Barbara Rommer’s study of dozens of frightening NDEs found that many served as motivation for experiencers to reconsider prior choices, thoughts, and beliefs.³³ NDE researcher Nancy Evans Bush, who herself had a frightening NDE while giving birth, has observed that those who healed most successfully from terrifying NDEs were people who interpreted their experience as a warning, connected it to behaviors they identified as unwise, and then found ways to change their lives for the better.³⁴

Margot Grey noted that people who had frightening NDEs also returned with an increased belief that life continues after death and a strong urge to radically modify their former way of life.³⁵

Consider the case of Frances Z., shared through Long’s NDERF website. Frances was a pill addict who attempted suicide by taking a hundred narcotic capsules with alcohol. During her cardiac arrest, she experienced leaving her body, descending into darkness, encountering demons, and finding herself in what she could only describe as hell, where she even encountered her own deceased father. Then, unexpectedly, she was pulled back up the tunnel and returned to her body. The aftermath was not trauma. It was transformation. Frances became sober. She remained sober for eighteen years and devoted herself to helping others avoid the misery she had experienced. Before her NDE, she described herself as “a nurse with no compassion.” Afterward, she was a different person entirely.⁵⁶

Frances’s story illustrates a pattern that appears throughout the frightening NDE literature. The experience serves as a profound moral and spiritual turning point. The transformation is not merely a psychological reaction to fear. It is a restructuring of the person’s entire value system—the same kind of deep, lasting change that we see in pleasant NDEs, but arrived at through a different doorway.

This is not what we would predict from a physicalist model. If NDEs are random hallucinations produced by dying brains, why would both pleasant and terrifying versions produce the same general trajectory of positive transformation? A pleasant hallucination might leave a lingering warm feeling. But a terrifying hallucination should leave lingering trauma—nightmares, anxiety, PTSD. And while some people do struggle with frightening NDEs, the overall pattern is transformation, not trauma. That is a pattern that makes sense if the experiencer genuinely encountered something real and returned with important information about what matters in life.

The Transformation–Veridical Connection

Here is where the cumulative case becomes very difficult for the skeptics to handle. NDE transformation does not exist in a vacuum. It exists alongside veridical evidence.

Consider a patient who, during cardiac arrest, reports leaving her body, watching the resuscitation team work on her, accurately describing specific events and details she could not have known, and then experiencing a transcendent encounter with a being of love. She returns to life permanently changed—less fearful of death, more compassionate, more spiritually oriented. And the details she reported about her resuscitation are confirmed by the medical staff.

The skeptic must now explain not just the transformation, but the transformation combined with the veridical perception. Marsh’s “crisis event” explanation cannot do this. People who are changed by surviving a bridge jump or a car accident do not report accurate observations of events they could not have seen. Fischer and Mitchell-Yellin’s Grand Canyon analogy cannot do this either. People who are changed by the Grand Canyon saw something real, yes—but they saw it with their own eyes, standing on the rim. NDE experiencers report seeing real things while their brains were flatlined.

The veridical evidence and the transformation evidence reinforce each other. The veridical evidence shows that something real was perceived. The transformation evidence shows that whatever was perceived produced lasting, positive, and distinctive changes that exceed what any known brain malfunction produces. Together, they form a powerful argument that the experiencer encountered genuine reality.

Dr. Bellg’s patient Naomi is a perfect example. During cardiac arrest, Naomi accurately described seeing the resuscitation team, watching them place a backboard under her body, and even reminded Bellg of something the doctor herself had forgotten—that she had grabbed supplies on the sterile field to keep them from falling when the team shifted Naomi’s body.³⁶ This level of specific, verified detail, occurring while Naomi was completely unconscious, cannot be explained by crisis psychology or neurological malfunction. And Naomi was also transformed by the experience. The two go together.

Another of Bellg’s patients, Carlita, was in a coma for thirteen days in the ICU. Bellg tested her responsiveness by pressing a thumbnail into the patient’s nail bed—there was absolutely no response. Yet when Carlita finally woke, she described watching Bellg examine her from outside her body. She accurately described the specific tests Bellg performed—the nail-bed pressure, the eye reflex tests, the sternal rub. She even noted that she could see the flashlight being shone in her eyes but did not feel the bright light herself, since she was watching from a different vantage point.³⁷ This woman was completely unresponsive to painful stimuli, and yet she accurately described what was being done to her body. Her experience did not just transform her. It contained verifiable information.

Marsh’s “Forgotten Potential” and What He Gets Right

I want to be fair to Marsh here, because on the subject of transformation, he actually makes some good points. In his concluding chapter, he laments what he calls “the forgotten potential of the post-experiential subject.”³⁸ He argues that the transformation NDE experiencers undergo is genuinely valuable—and that researchers have been so obsessed with the otherworldly content of NDEs that they have neglected the real-world impact on the people who have them.

Marsh suggests that the insights gained by NDE experiencers “could be harnessed for the amelioration of society,” for instance in the caring professions or personal counseling.³⁹ He proposes that future research should focus on the transformed lives of NDE experiencers rather than trying to determine whether NDEs offer a genuine glimpse of the hereafter. He asks, in effect: wouldn’t it be more valuable to study how these people became so compassionate than to debate whether they really left their bodies?

I appreciate Marsh’s concern for the experiencers themselves. He is right that the post-experiential dimension deserves more serious study. He is right that some NDE authors have been so focused on proving the afterlife that they have given insufficient attention to the human beings whose lives were changed. And he is right that the transformation has practical value regardless of what caused it.

In fact, Marsh’s theology of personhood is one of the more interesting parts of his book. Drawing on the concept of human “becoming”—the idea that each person is always in the process of becoming who they are meant to be—Marsh argues that the post-experiential transformation represents the actualization of human potential. He connects this to the theological concept of transcendence: the capacity to reach beyond oneself, to act freely, and to grow toward something greater.⁵⁷ This is genuinely thoughtful theology, and I find much to agree with in it.

Where Marsh goes wrong is in his assumption that affirming the value of post-experiential transformation requires us to deny the reality of the experience that produced it. He writes that the post-experiential change is “the result of undergoing an ECE”—but he means by this that the brain event itself, regardless of whether it corresponded to any external reality, produced the change.⁵⁸ He wants to have the transformation without the transcendence. He wants the fruit without the root.

But this creates a problem for his own theology. Marsh argues that human personhood is characterized by freedom and transcendence—the capacity to reach outward, to act, to grow beyond one’s present limitations. If NDE experiencers are exhibiting this kind of transcendence in their transformed lives, what produced it? On the substance dualist view, the answer is straightforward: they encountered a transcendent reality, and that encounter activated the transcendent dimension of their own nature. On Marsh’s physicalist view, the answer is much harder to come by. A brain malfunction activated their capacity for transcendence? A hallucination produced by oxygen-starved neurons generated the most profound spiritual growth of their entire lives? That is a lot of weight to place on random neurochemistry.

But here is where Marsh goes wrong in a different way. He sets up a false either/or. He suggests we should study the transformation instead of investigating whether the NDE was real. But why not do both? The transformation and the veridicality of NDEs are not competing interests. They are complementary pieces of the same puzzle. When a patient accurately perceives events during cardiac arrest and comes back permanently transformed, studying one without the other is like studying only half a photograph.

Marsh also disputes the claims of Ring and Grey that NDE experiencers tend to move away from organized religion toward more individualized spirituality. He cites studies by Sabom and Amber Wells suggesting that what actually changed in many NDE experiencers was “a heightened sense of internal religiosity in faith, strength of belief, increased spirituality and the meaning of the religious conviction in their lives.”⁴⁰ This is an interesting correction, and it aligns with J. Steve Miller’s research showing that NDEs often reinforce rather than undermine Christian faith (as we discussed in Chapter 28). The point is that NDE transformation is not a simple slide toward New Age spirituality, as some critics assume. It is more nuanced and more varied than either side sometimes acknowledges.

What About the Fischer and Mitchell-Yellin’s “Out-of-Body Perspective” Theory?

Fischer and Mitchell-Yellin end their chapter on transformation with an intriguing idea. They suggest that the out-of-body component of an NDE might produce moral transformation by giving the experiencer a detached perspective—literally rising above their own body and seeing things from a broader vantage point. This new perspective, they argue, is “at least a first step toward taking what many regard as the distinctively moral perspective” of putting oneself in another’s shoes.⁴¹

It is a clever idea. And it is not entirely wrong. Seeing yourself from the outside almost certainly does contribute to a broadened perspective. But notice what Fischer and Mitchell-Yellin are doing here. They are offering a physicalist explanation for how an OBE could produce moral change. What they are not doing is explaining why the brain would produce an OBE in the first place. If the OBE is just a hallucination, why would the brain generate an experience that happens to have such a useful moral structure? And why would only some cardiac arrest patients get this “useful hallucination” while most do not?

Moreover, their explanation only addresses the OBE component. It says nothing about the life review, the encounter with deceased loved ones, the being of light, or the overwhelming sense of unconditional love. These are not just changes in perspective. They are encounters with specific content—content that, if real, would explain the transformation perfectly, and that, if illusory, requires a very complicated story about why the dying brain would generate such consistently positive and morally enriching content.

The simplest explanation remains the most obvious one. NDE experiencers are transformed because they encountered something real. They experienced consciousness continuing beyond the body, love beyond anything they had known, and a reality more vivid and more true than anything in ordinary waking life. They came back different because they had genuinely been somewhere different. And the transformation, far from being an embarrassment to the NDE case, is one more strand in a cumulative argument that keeps getting stronger.

Cross-Cultural Consistency

One final point deserves attention. The transformation produced by NDEs is remarkably consistent across cultures, religions, and time periods. Carter notes that the same basic aftereffects—reduced fear of death, increased compassion, decreased materialism, enhanced spirituality—appear whether the experiencer is an American Christian, a Dutch atheist, an Indian Hindu, or a Japanese Buddhist.⁴² The specific religious language varies. The core transformation does not.

This cross-cultural consistency is difficult to explain on a purely physicalist model. If NDEs are hallucinations shaped by cultural expectations, we should expect the aftereffects to vary by culture too. An American Christian who hallucinates heaven might come back more devout. A Dutch atheist who hallucinates random neural noise should not come back more spiritual. But they do. Consistently. The transformation cuts across every cultural and religious boundary, suggesting that it arises from contact with something universal—not from culturally conditioned brain chemistry.

What Long’s NDERF Data Tells Us

Jeffrey Long’s massive Near-Death Experience Research Foundation (NDERF) database provides perhaps the largest collection of NDE accounts in existence. While his data collection methods are different from the prospective hospital studies of van Lommel and Sabom—Long gathers accounts primarily through his website, which means he cannot independently verify medical records in most cases—the sheer volume of accounts allows him to identify patterns that smaller studies cannot.

Long’s work on NDE aftereffects confirms and extends what the clinical studies have shown. NDE experiencers consistently report profound life changes. Most feel that the NDE was the single most significant event of their lives. They report a deep certainty—not a hope, not a wish, but a certainty—that life continues beyond the death of the body. They report that their priorities have been completely restructured, with love and relationships taking precedence over career advancement, material wealth, and social status.⁵³

Long also makes an important point about the reluctance of NDE experiencers to share their stories. If transformation were the product of wishful thinking or attention-seeking, we would expect experiencers to be eager to broadcast their stories. The opposite is true. Many NDE experiencers keep their experiences secret for years or even decades, fearing ridicule. When van Lommel re-interviewed his patients, he found that NDE memories remained remarkably stable over time—they did not embellish or fade, as fabricated stories tend to do.⁵⁴ The experiencers are not performing for an audience. They are quietly living out the implications of something that happened to them when they were clinically dead.

The Theological Dimension: Why Transformation Matters for the Christian Case

I have argued throughout this book that the primary evidence for NDEs is empirical—we follow the data where it leads. But let me take a moment to note how NDE transformation connects to Christian theology, because the fit is striking.

The Bible teaches that encountering God transforms people. Moses came down from Sinai with his face shining so brightly that the Israelites could not look at him (Exod. 34:29–35). Isaiah encountered God in the temple and was immediately convicted of his sinfulness and called to prophetic ministry (Isa. 6:1–8). The disciples encountered the risen Christ and were transformed from frightened men hiding in an upper room into bold preachers who turned the world upside down. Paul met Christ on the Damascus road and went from persecuting Christians to dying for the faith.

In every case, the pattern is the same: encounter with transcendent reality produces lasting, radical transformation. The encounter is not just an idea. It is not just an argument. It is a meeting—a confrontation with a reality so overwhelming that the person cannot go back to who they were before.

NDE transformation follows this same pattern. The experiencer does not simply learn a new piece of information. They encounter something—a reality of love and light and consciousness so far beyond ordinary experience that it restructures everything they thought they knew about the world. And the transformation lasts. It deepens. It does not fade with time but grows stronger, just as the transformation of the biblical figures grew stronger over the course of their lives.⁵⁵

I am not claiming that every NDE is a vision from God. NDEs are complex experiences, and their content must be evaluated carefully against Scripture (as we discussed in Chapter 28). But the pattern of NDE transformation—the lasting, deepening, positive restructuring of the person’s values and identity after encountering transcendent reality—is exactly what Christian theology predicts should happen when a human being comes into contact with the divine. Physicalism predicts nothing of the sort. Hallucination theory predicts nothing of the sort. But the biblical worldview, in which human beings are body-and-soul creatures capable of encountering spiritual reality, predicts it perfectly.

Why This Matters for the Cumulative Case

So where does all of this leave us? The transformation evidence, taken by itself, does not prove that NDEs are real encounters with a transcendent reality. I have said that several times, and I mean it. But the transformation evidence, when placed alongside everything else we have discussed in this book, adds significant weight to the cumulative case.

Think of it this way. If you had only the veridical evidence—the patients who accurately reported events during cardiac arrest—a skeptic could say, “Maybe they got lucky guesses.” If you had only the blind NDE evidence, a skeptic could say, “Maybe blind people have residual visual processing.” If you had only the children’s NDE evidence, a skeptic could say, “Maybe children absorb information from adults.” If you had only the transformation evidence, a skeptic could say, “Maybe crisis events just change people.”

But we do not have only one piece of evidence. We have all of them. And each piece makes the others stronger. The veridical evidence shows that the NDE involved real perception. The transformation evidence shows that whatever was perceived had lasting, positive, and distinctive effects. The children’s evidence shows that the pattern appears even in people too young to have cultural expectations about NDEs. The cross-cultural evidence shows that the pattern appears regardless of the experiencer’s beliefs. The blind NDE evidence shows that the pattern includes visual perception in people who have never had visual experience. And the deepening of transformation over time shows that the experience is qualitatively different from anything that hallucinations, dreams, or generic crisis responses produce.

Every strand in the rope matters. Transformation is one of those strands. And it is a strong one.

D. Counter-Objections

“It’s a Placebo Effect”

A skeptic might argue that NDE transformation is essentially a placebo effect. The experiencer believes they had a real encounter with the afterlife, and that belief changes them—just as a sugar pill can cure a headache if the patient believes it is real medicine. The transformation is real, but its cause is subjective belief, not objective reality.

This is a reasonable objection, and it deserves a careful response. The placebo analogy is initially appealing because it offers a mechanism: the experiencer’s belief in the reality of the experience drives the psychological change. On this view, it does not matter whether the NDE was “real” or not. What matters is that the person thinks it was real, and that belief restructures their psychology.

But there are serious problems with this explanation. First, as we noted above, the Groth-Marnat and Summers study controlled for this by comparing NDE experiencers with people who had equally life-threatening experiences but no NDE. If the transformation were simply a response to believing you almost died, both groups should show similar changes. They do not. The NDE group shows significantly more change, and the depth of the NDE predicts the depth of the change.⁴³

Second, the “placebo” framing actually concedes too much to the skeptic. In medicine, we know that placebos work because the mind influences the body. But NDE transformation is not just a temporary physiological response. It is a restructuring of values, priorities, and personality that deepens over years. Placebo effects do not typically intensify over eight years. They tend to diminish as the initial expectation wears off. NDE transformation does the exact opposite. It grows stronger. Something more than belief is at work.

Third, and most importantly, the placebo objection does not address the veridical evidence. If the experience is “just a belief,” how did the patient acquire accurate information about events they could not have perceived? A placebo does not give you information you did not previously have. A person who takes a sugar pill may feel better, but the sugar pill does not enable them to describe specific events happening in another room. The veridical component of many NDEs breaks the placebo model.

Finally, the placebo analogy actually undermines itself in a subtle way. Placebos work best when the patient genuinely believes in the treatment. If NDE experiencers genuinely believe their experience was real—and most do, with rock-solid conviction—then calling it a “placebo” amounts to saying: “Their belief is so deep and so unshakeable that it permanently restructured their personality.” That is a remarkable admission. It means the experience was subjectively so powerful, so convincing, and so overwhelming that it produced a lifelong change in the person’s deepest identity. At some point, a hallucination that is that powerful, that coherent, that consistent across millions of people worldwide, and that produces that much lasting good starts to look less like a brain malfunction and more like a genuine encounter with reality.

“Selection Bias—Only Transformed People Report NDEs”

Another objection: perhaps the people who report NDEs are the same people who were already inclined toward spiritual transformation. Maybe NDEs do not cause the transformation; maybe a certain type of person is both more likely to have an NDE and more likely to be transformed by a crisis.

The prospective studies address this directly. Van Lommel’s study collected data from all cardiac arrest survivors at the participating hospitals, not just those who volunteered to discuss NDEs. Of the 344 patients, only 62 reported NDEs. There was no significant difference in prior religious belief, prior psychological profile, or demographic factors between the NDE group and the control group.⁴⁴ The groups started out similar. They ended up very different. The NDE was the variable.

Moreover, this objection does not explain the depth-transformation correlation. If the transformation were driven by a pre-existing personality type rather than by the NDE itself, we would expect all experiencers to show similar levels of change regardless of NDE depth. But that is not what happens. Deeper NDEs produce deeper changes. The pre-existing personality cannot explain that pattern. Only the experience itself can.

“The Psychedelic Comparison Defeats the NDE Argument”

Fischer and Mitchell-Yellin argue that psychedelic drugs can produce transformations similar to those caused by NDEs, and that since psychedelic experiences are physically caused, NDE transformation is probably physically caused too.⁴⁵

I addressed this briefly above, but let me expand. The psychedelic comparison is interesting, but it does not lead where the skeptics want it to go. Yes, psilocybin and other substances can produce lasting positive changes. But the question is why. Many psychedelic researchers have moved away from a purely materialist interpretation of these experiences. The striking parallels between psychedelic experiences and NDEs—the sense of encountering ultimate reality, the dissolution of the ego, the experience of unconditional love, the lasting transformation—have led some researchers to conclude that both may involve contact with a dimension of reality that the brain normally filters out.⁴⁶ On this view, psychedelic substances do not create the experience; they open a door that the brain normally keeps closed—just as cardiac arrest may open that same door by disrupting the brain’s filtering function.

This is consistent with the filter/transmission model of consciousness, which we discussed in Chapter 16. If the brain is a receiver or filter of consciousness rather than a generator of it, then both psychedelics and cardiac arrest could remove the filter—with similar results. The psychedelic comparison, far from defeating the NDE argument, may actually support it.

Furthermore, there is a crucial difference between psychedelic transformation and NDE transformation: the veridical element. Psychedelic experiencers do not report verifiable perceptions of events in the physical world during their trips. NDE experiencers do. The transformation may look similar, but the NDEs come with an evidential bonus that psychedelic experiences lack.

Conclusion: Another Strand in the Rope

The transformative power of NDEs is not, by itself, proof that NDEs are genuine encounters with a reality beyond the physical. The critics are right about that. But the critics are wrong to treat transformation as evidentially irrelevant. When you consider the distinctive pattern of NDE aftereffects—their consistency across cultures, their persistence and intensification over years, their correlation with the depth of the experience, their dramatic difference from ordinary crisis responses, and their connection to veridical perception—you are looking at a piece of evidence that fits naturally into the hypothesis that NDEs are real and fits very awkwardly into the hypothesis that they are hallucinations.

Marsh admits the transformation is real. Fischer and Mitchell-Yellin admit the transformation is profound. Both struggle to explain why a hallucination produced by a dying brain would consistently produce the deepest, most lasting, and most morally enriching personality changes that researchers have ever documented.

Think about what the skeptics are asking us to believe. They want us to accept that a malfunctioning brain, starved of oxygen, flooded with random neurochemicals, just happens to generate an experience so coherent, so meaningful, and so overwhelmingly positive that it restructures the experiencer’s personality for the rest of their life. Not occasionally. Consistently. Across cultures. Across decades. In patients young and old, religious and atheist, educated and uneducated. The dying brain, on the skeptics’ model, is the most brilliant therapist in the world—producing in a few moments of cardiac arrest what years of counseling, meditation, and intentional spiritual practice often fail to produce.

Or we could accept the simpler explanation. NDE experiencers are transformed because they encountered something real. They experienced consciousness continuing beyond the body, love beyond anything they had known, and a reality more vivid and more true than anything in ordinary waking life. They came back different because they had genuinely been somewhere different.

A rope is made of many strands. No single strand holds all the weight. But when you weave them together—veridical perception, blind NDEs, children’s NDEs, cross-cultural consistency, the failure of neurological explanations, and the remarkable transformative aftereffects—you get a rope that is very, very strong. The transformation evidence is one more strand. And the rope keeps holding.
