An experience, either spontaneous or induced, in which one’s center of consciousness seems to be in a spatial location outside of one’s physical body; Celia Green distinguishes two types of such “ecsomatic” [From the Greek ek, “out of,” + soma, “body”] experiences: the “parasomatic” [From the Greek para, “along side of”] in which the person appears to themselves to possess a duplicate body, sometimes connected to the physical body by a “silver cord;” and the “asomatic” [From the Greek a-, “without”] in which they feel themselves to be entirely bodiless; in either case, many experients claim to perceive their physical bodies lying inert, to see and hear people while remaining unperceived themselves, and to perceive objects and events normally beyond the range of their physical senses; of special interest to parapsychologists on account of its alleged connection with clairvoyance, and to students of survival as providing an example of what disembodied existence could be like. The term “OBE” is preferred by parapsychologists for the phenomena also known as “astral projection,” “traveling clairvoyance.” See also Astral Body. [Dale & White, 1977]
