A near-death experience (NDE) is a personal experience associated with death or impending death, encompassing multiple possible 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][2][3]
Explanatory models for the NDE can be divided into several broad categories, including psychological, physiological, and transcendental explanations.[1][4][5][6] Research from neuroscience considers the NDE to be a hallucinatory state caused by various physiological and psychological factors.
