“The Psychology of Life After Death”, Ronald K. Siegel1980-10-01 (, , , ; similar)⁠:

Traditionally, people’s concern with an afterlife has been of interest only to philosophy and religion. The recent explosion of popular articles and books about life after death has now reached the medical and psychiatric journals, in which “scientific” reports cite evidence from survivors of clinical death and from deathbed visions of terminal patients, among other sources of data. This article critically reviews the evidence in light of ethological, anthropological, and psychological findings. The similarity of afterlife visions to drug-induced hallucinations invites a rational framework for their experimental analysis. From observations of animals burying their dead, through awareness of the seasonal rebirth of nature, to recognition of inherited characteristics, early homo sapiens developed the concept of life after death in an effort to explain these behaviors and their underlying feelings. Cross-cultural studies confirm that the experiences of dying and visiting “the other side” involve universal elements and themes that are predictable and definable. These phenomena arise from common structures in the brain and nervous system, common biological experiences, and common reactions of the central nervous system to stimulation. The resultant experience can be interpreted as evidence that people survive death, but it may be more easily understood as a dissociative hallucinatory activity of the brain.
