The earliest accounts of NDE can be traced to the Myth Of Er, recorded in the 4th century BC by Plato's The Republic (10.614-10.621), wherein Plato describes a soldier telling of his near-death experiences. The traits of a classic NDE are as follows: A sense/awareness of being dead. A sense of peace, well-being and painlessness. An out of body experience. A "tunnel experience". A rapid movement toward and/or sudden immersion in a powerful light. An intense feeling of unconditional love. Encountering "Beings Of Light". Receivjng a life review or preview. Receiving knowledge about one's life and the nature of the universe. A reluctance to return. Hearing music. Telepathic conversations with beings of light or angels, deceased relatives and pets, or religious figures. From Wikipedia Cover by Hieronymous Bosch-Ascent of the Blessed.
