out-of-body experience

An out-of-body experience (OBE or sometimes OOBE), is an experience that typically involves a sensation of floating outside of one's body and, in some cases, perceiving one's physical body from a place outside one's body (autoscopy). About one in ten people has had an out-of-body experience at some time in their lives. Scientists know little about the phenomenon. OBEs are often part of the near-death experience, and reportedly may also lead to astral projection. It is claimed that OBErs sometimes observe details during an OBE which were unknown to them beforehand.
