Chapter 2
Imagine this. Your heart stops in a hospital bed. Within about ten seconds, the squiggly line on the EEG monitor — the little graph that tracks your brain’s electrical activity — goes flat. Your pupils stop reacting to light. By every clinical measure that matters, you are gone.
But your story is not over. Minutes later, maybe longer, the team gets your heart started again. They stabilize you. You wake up. And you begin telling people what you saw.
You saw the room from up near the ceiling. You watched the doctors and nurses working on your body. You felt no fear, only an enormous calm, a kind of peace you have never felt before. There was a passageway, or a tunnel, and a light at the end of it that seemed to know you. You met someone — a grandmother who died when you were small, a friend lost to cancer. You were shown your life in a single instant. You were sent back. And then you woke up sore and confused in the recovery room.
Some version of that story has been told tens of thousands of times in the last fifty years. The question driving this whole book is whether the people telling it are telling us something real.
Before we can get to that question, we have to be clear about what we are even talking about. That is the work of this chapter.
The phrase near-death experience — usually shortened to NDE — was coined by an American medical student named Raymond Moody in 1975. Moody was finishing his psychiatry training when he started gathering reports from people who had been resuscitated after cardiac arrest, severe trauma, or other brushes with death. His book Life After Life introduced the term to the public and sold over thirteen million copies.1 The label stuck because no one had a better one.
For our purposes, an NDE is a profound conscious experience reported by a person who has either come very close to death, been resuscitated from clinical death, or in some cases passed through a serious medical crisis without actually dying. The experience tends to involve a recognizable cluster of features. It is remembered with unusual clarity, often years later. And it usually changes the person who had it.2
Notice what that working definition does and does not say. It says these are experiences — first-person reports about what someone perceived, felt, or thought during a medical emergency. It does not say where those experiences come from. That is the whole question. A skeptic and a believer can agree that NDEs are a real category of human reporting and still disagree, sharply, about what those reports actually are. Marsh and the pro-NDE researchers do agree on this much: people are not making the reports up.3 The disagreement is over what is happening behind the report — a confused brain, or a conscious soul.
Moody identified fifteen elements that showed up over and over again in his interviews. Not every NDEr reports every element — nobody does. But the same handful of features keep appearing across thousands of cases, in different countries, decades apart, in patients with no prior knowledge of the literature.4 The radiologist Jeffrey Long, who runs the world’s largest online database of NDE accounts, has refined Moody’s list into twelve elements that appear in fairly stable order.5
The most evidentially important feature, for the purposes of this book, is the out-of-body component. The experiencer perceives the scene around the body from a vantage point outside the body — usually somewhere up near the ceiling, sometimes farther afield. They report watching the resuscitation, hearing what is said, noticing details. We will spend a lot of time on this one.
Other common features include: a sense of moving through a tunnel or dark passage; an encounter with a brilliant light that radiates love and acceptance; a meeting with deceased relatives or with a being many experiencers describe as Christ; an instantaneous review of the experiencer’s life with all its consequences laid bare; an overwhelming sense of peace and absence of pain; a perceived boundary the experiencer is told not to cross; and a return, often involuntary, to the body. Most NDErs say their thinking during the experience felt clearer than normal waking thought, not foggier.6
Researchers sometimes split NDEs into shallow and deep. A shallow NDE may include only a couple of features — a feeling of peace, a sense of leaving the body. A deep NDE may include nearly all of them. The phenomenon is a spectrum, not a single thing. That matters because critics sometimes pick a thin or fragmentary case and use it to dismiss the whole field. The strong evidential cases tend to be deep ones.
For thirty years, the standard tool for sorting NDEs from non-NDEs has been the Greyson Scale. It was developed in 1983 by Bruce Greyson, then a psychiatrist at the University of Michigan, in a paper published in the Journal of Nervous and Mental Disease.7 Greyson wanted a quantitative way to identify true NDEs in clinical research, so he could tell them apart from ordinary fainting, panic attacks, surgical dreams, and the kind of vague pleasant feeling someone might have after a close call.
The scale asks sixteen questions, each scored from zero to two. The questions cluster into four components: cognitive (was your thinking faster than usual? did your life flash before you?), affective (did you feel overwhelming peace? did you see a brilliant light?), paranormal (did you seem to leave your body? did you sense events at a distance?), and transcendental (did you encounter a mystical being? did you reach a point of no return?).8 The total score runs from zero to thirty-two. The conventional cutoff is seven. Score below that, and your experience does not qualify as an NDE for research purposes. Score seven or higher and it does. The cutoff is somewhat arbitrary, like every diagnostic threshold, but Greyson chose it carefully and the field has stuck with it.
Two things about the Greyson Scale are worth pausing on. The first is that it has held up under decades of testing. Greyson followed the original validation study with a long series of reliability tests. He showed that NDErs scored on the scale today produced essentially the same scores when re-tested twenty years later — a striking finding for self-reported memory data, and one that already starts to push back against the “false memory” objection we will hear from critics in Chapter 18.9 The second is that the scale is conservative. It was built to exclude doubtful cases, not inflate the count. A vague feeling of peace during fainting will not get you to seven. Neither will a pleasant dream after surgery. The scale takes a story and asks whether it really has the structural features of a deep NDE before counting it as one. That is a feature, not a bug.
The scale’s track record is why modern studies — van Lommel’s landmark Lancet paper, the AWARE trials, the NDERF survey — all use the Greyson Scale to filter their cases.10 When this book talks about an NDE, it generally means an experience that would meet that threshold.
Out-of-body experiences (OBEs) and near-death experiences are related, but they are not the same thing. Pulling them apart matters, because the bulk of the evidential weight in this book rests on the OBE component, not on the NDE as a whole.
An OBE is the perception of being separate from one’s body. The experiencer feels, and sometimes reports seeing, themselves from a viewpoint outside their physical location. OBEs can happen during cardiac arrest. They can also happen, much less commonly, during ordinary anesthesia, deep meditation, the moments before falling asleep, certain epileptic seizures, or after a hard knock to the head. Estimates of how many people have had at least one OBE in their lives run as high as one in ten.11
An NDE is the broader cluster of experiences I described earlier. It usually includes an OBE-like component — especially in its early phase — but adds the tunnel, the light, the encounters, the life review, and the boundary. Michael Sabom, the cardiologist whose 1982 work first put NDE research on a serious clinical footing, distinguished the OBE component (which he called autoscopic) from the deeper, otherworldly part (which he called transcendental).12 Sabom’s point was that these two parts of an NDE are evidentially different. The transcendental part — tunnels, light, deceased loved ones — cannot easily be checked. Either you trust the experiencer or you do not. But the autoscopic part can sometimes be checked. The experiencer reports specific things about the room, the team, the equipment, the conversation. Some of those things can be verified.
Notice what this means for the argument of this book. I am not asking you to believe that every detail of every NDE is true. I am not asking you to take the experiencer’s description of meeting a deceased grandmother as proof of an afterlife. The case I am building does not rest there, and it does not need to. It rests on the smaller, harder, more checkable subset: the OBE component during cardiac arrest, when the experiencer reports specific things about the resuscitation that turn out to be accurate, that they could not have known by ordinary means, and that occurred during a window when the brain was, by every clinical standard, not capable of producing perception.
That is the wedge this book leans on. We will spend the next several chapters on it.
Common enough that they are not a fringe phenomenon. Older Gallup-style surveys put the rate at roughly five percent of American adults — that is, about one in twenty.13 Among people who actually survive cardiac arrest, the rate is much higher: van Lommel’s Lancet study found that eighteen percent of his Dutch resuscitation patients reported an NDE, and other prospective hospital studies have produced similar numbers.14 Whatever NDEs are, they are not rare. If we take the conservative five-percent figure as a floor, we are talking about something on the order of fifteen million American adults walking around right now who report having had one. Any working theory of consciousness has to account for them.
Now we come to the term that does the heavy lifting in this book: veridical.
The word means “corresponding to reality.” A veridical NDE is one in which the experiencer reports perceiving something during the experience that turns out to be objectively, externally true — and that they could not have known by ordinary means. Not just felt true. Not just emotionally compelling. Verifiably true.
KEY ARGUMENT — Why veridical NDEs are the evidential core. A subjective NDE feature — a feeling of peace, a sense of moving through a tunnel, an encounter with a brilliant light — can always, in principle, be explained as something the brain produced. We cannot check those features against external reality. But a veridical NDE includes content that can be checked. When a cardiac-arrest patient correctly describes a specific instrument she has never seen, identifies a person she has never met, or reports a conversation that occurred down the hall while her brain was non-functional, we are no longer stuck inside her head. The claim has been brought into the open air. It can be tested. That is why this book leans hard on veridical cases.
The psychologist Janice Holden has been the field’s most careful tabulator of these cases. In her chapter for the 2009 Handbook of Near-Death Experiences, she identified 107 reports of apparently veridical perception during NDEs, drawn from thirty-nine separate publications by thirty-seven different authors. Using a strict standard — if even one detail in a case turned out to be wrong, the whole case was scored as inaccurate — she found that only eight percent of the 107 cases involved any inaccuracy at all. Thirty-seven percent had been independently verified by external sources.15 That is a remarkable batting average for any kind of human testimony, let alone testimony from people whose hearts had stopped.
We met one such case in Chapter 1 — the dentures man from van Lommel’s Dutch hospital study. Chapter 4 will lay out two or three more of the strongest. Chapter 5 will give the famous Pam Reynolds case its own focused treatment, including all six of Marsh’s objections to it. The point for now is just this: when this book talks about “the evidence” for NDEs, it almost never means the subjective glow of the experience. It means the verifiable subset. The veridical core.
Before we move on, a word about vocabulary — because Michael Marsh, our main interlocutor, does not like the standard terms. Throughout his book he replaces “OBE” with ECE — extra-corporeal experience — and he uses “ECE” far more often than “NDE” or “OBE.” His preface explains the move. He thinks “near-death experience” smuggles a metaphysical claim into the descriptor itself: near-death already suggests that the person was, in some serious sense, dead, and that the experience belongs to that condition. He wants a more neutral term.16
I take Marsh’s concern seriously. Vocabulary shapes argument. But I am not going to follow him on this, for three reasons.
First, “near-death” is not actually a metaphysical claim. It is a description of the trigger. These experiences occur, with rare exceptions, in the context of cardiac arrest, severe trauma, surgical complication, or other moments where the body is failing. Calling that context “near-death” is just accurate. Whether the person was actually dead in some philosophical sense is a separate question, and the standard term does not settle it either way.
Second, Marsh’s preferred term is itself loaded. Extra-corporeal means “outside the body.” That phrasing assumes the experiencer was not, in fact, outside the body — that the experience only seemed extra-corporeal. In other words, ECE quietly bakes Marsh’s own conclusion into the word he uses to describe the data. If anyone is begging the question with their vocabulary, it is not the field.
Third, “NDE” and “OBE” are the terms used by Greyson, van Lommel, Sabom, Long, Parnia, Holden, the AWARE trials, and the major reference works. Switching vocabulary mid-conversation would cut this book off from the fifty-year scholarly tradition it is engaging.17 So I will continue to use NDE and OBE, with a clear conscience. When Marsh uses ECE, I will note it, but I will not adopt it.
A NOTE ON FAIRNESS. Marsh is right that some terminology in this field has been sloppy, and that early NDE writers sometimes wrote as if the metaphysical question were settled by the descriptors. He is also right that hype has clouded the literature in places. Where critics like Marsh and Fischer and Mitchell-Yellin push the field to be more rigorous, they make us better. Throughout this book I want to honor the legitimate parts of their critique even as I argue, hard, that their conclusions miss the strongest evidence.18
So here is where we stand. An NDE is a profound, recognizable, well-documented kind of human experience. It occurs near death, especially during cardiac arrest. It has a stable cluster of features that show up across cultures and decades. It can be measured by the Greyson Scale. It includes, in many cases, an out-of-body component — and that component, unlike the rest, can sometimes be checked against external reality. The cases where the check comes back positive are the veridical NDEs, and they are the evidential core of everything that follows in this book.
Notice what we have not done in this chapter. We have not argued that NDEs prove the existence of an afterlife. We have not argued that the soul departs the body during a cardiac arrest. We have not even argued that consciousness can exist apart from the brain. Those are conclusions, not starting points, and they will need to be earned chapter by chapter. What we have done here is much smaller. We have set out the vocabulary, the measuring tool, and the kind of case that will carry the evidential weight when we get there.
One question remains before we look at those cases up close: where did NDE research come from, and how seriously should we take the people doing it? Chapter 3 tells that story — how a tiny field built on Moody’s 1975 interviews grew into a body of peer-reviewed, prospective, hospital-based studies that the major medical journals are now publishing. Then, with the foundations in place, we will turn in Chapter 4 to the strongest cases the field has produced.
