A near-death experience (NDE) is a personal experience associated with death or impending death. Such experiences may encompass a variety of sensations including detachment from the body, feelings of levitation, total serenity, security, warmth, the experience of absolute dissolution, and the presence of a light.[1]

Neuroscience research suggests that an NDE is a subjective phenomenon resulting from "disturbed bodily multisensory integration" that occurs during life-threatening events.[2] NDEs are a recognized part of some transcendental and religious beliefs in an afterlife.[6]
