An out-of-body experience (OBE or sometimes OOBE) is a subjective experience that typically involves a sensation of floating outside of one’s body and, in some cases, seeing one’s physical body from a place outside one’s body (autoscopy). Approximately one in ten people claim to have had an out-of-body experience at some time in their lives. For some, the phenomenon occurs spontaneously, while for others it is linked to dangerous circumstances, a dream-like state, a near-death experience, or the use of psychedelic drugs. A few have been able to induce the experience deliberately through visualizations while in a relaxed, meditative state, or through a lucid dream. Relatively little is known with certainty about OBEs.
