Probably not.  Dr. Raymond Moody, in his 1975 book Life After Life, created the term "near-death experiences" to describe the clinical death experiences of people he had interviewed.  However, although being close to death is a fairly reliable "trigger," identical experiences happen under very different circumstances, even to people who are in no way close to physical death.  The best known experiences are those of saints and religious mystics.  Deep prayer and meditation can produce events like NDEs, as can other altered states of consciousness, without the person being near physical death.
