What is Out-of-body experience?
An out-of-body experience (OBE or OOBE) is when a person sees the world from a place outside their body. An OBE is a type of autoscopy, which means “seeing yourself.” This term is more commonly used to describe the condition of seeing a second self, or doppelgänger. The term “out-of-body experience” was first used in 1943 by G. N. M. Tyrrell in his book Apparitions. It was used by researchers like Celia Green and Robert Monroe as an alternative to labels like “astral projection” or “spirit walking,” which are more based on beliefs. OBEs can be caused by things like traumatic brain injuries, sensory deprivation, near-death experiences, dissociative and psychedelic drugs, dehydration, sleep disorders, dreaming, and electrical stimulation of the brain, as well as many other things that happen to the brain. It can also be done on purpose by some people. Most people have an OBE once or several times in their lives. One in ten people have an OBE at least once. Psychologists and neuroscientists think of OBEs as dissociative experiences that happen because of different psychological and neurological factors.
