One cannot travel far in spiritual circles without meeting people who are fascinated by the “near-death experience” (NDE). The phenomenon has been described as follows:
Frequently recurring features include feelings of peace and joy; a sense of being out of one’s body and watching events going on around one’s body and, occasionally, at some distant physical location; a cessation of pain; seeing a dark tunnel or void; seeing an unusually bright light, sometimes experienced as a “Being of Light” that radiates love and may speak or otherwise communicate with the person; encountering other beings, often deceased persons whom the experiencer recognizes; experiencing a revival of memories or even a full life review, sometimes accompanied by feelings of judgment; seeing some “other realm,” often of great beauty; sensing a barrier or border beyond which the person cannot go; and returning to the body, often reluctantly.
(E.F. Kelly et al., Irreducible Mind: Toward a Psychology for the 21st Century. New York: Rowman and Littlefield, 2007, p. 372)
Such accounts have led many people to believe that consciousness must be independent of the brain. Unfortunately, these experiences vary across cultures, and no single feature is common to them all. One would think that if a nonphysical domain were truly being explored, some universal characteristics would stand out. Hindus and Christians would not substantially disagree—and one certainly wouldn’t expect the after-death state of South Indians to diverge from that of North Indians, as has been reported. It should also trouble NDE enthusiasts that only 10−20 percent of people who approach clinical death recall having any experience at all.
However, the deepest problem with drawing sweeping conclusions from the NDE is that those who have had one and subsequently talked about it did not actually die. In fact, many appear to have been in no real danger of dying. And those who have reported leaving their bodies during a true medical emergency—after cardiac arrest, for instance—did not suffer the complete loss of brain activity. Even in cases where the brain is alleged to have shut down, its activity must return if the subject is to survive and describe the experience. In such cases, there is generally no way to establish that the NDE occurred while the brain was offline.
Many students of the NDE claim that certain people have left their bodies and perceived the commotion surrounding their near death—the efforts of hospital staff to resuscitate them, details of surgery, the behavior of family members, etc. Certain subjects even say that they have learned facts while traveling beyond their bodies that would otherwise have been impossible to know—for instance, a secret told by a dead relative, the truth of which was later confirmed. Of course, reports of this kind seem especially vulnerable to self-deception, if not conscious fraud. There is another problem, however: Even if true, such phenomena might suggest only that the human mind possesses powers of extrasensory perception (e.g. clairvoyance or telepathy). This would be a very important discovery, but it wouldn’t demonstrate the survival of death. Why? Because unless we could know that a subject’s brain was not functioning when these impressions were formed, the involvement of the brain must be presumed.
