A near-death experience, or NDE, is a profound psychological event that may occur to a person close to death or who is not near death but in a situation of physical or emotional crisis. Being in a life-threatening situation does not, by itself, constitute a near-death experience. It is the pattern of perceptions, creating a recognizable overall event, that has been called “near-death experience.” An NDE may begin with an out-of-body experience—a very clear perception of being somehow separate from one’s physical body, possibly even hovering nearby and watching events going on around the body. An NDE typically includes a sense of moving, often at great speed and usually through a dark space, into a fantastic landscape and encountering beings that may be perceived as sacred figures, deceased family members or friends, or unknown entities. A pinpoint of indescribable light may grow to surround the person in brilliant but not painful radiance; unlike physical light, it is not merely visual but is sensed as being an all-loving presence that many people define as the Supreme Being of their religious faith.
