Out of Body Experiences
Out of Body Experiences (OBEs) are a state of mind which often occurs as a result of near death experiences or psychedelics use (most prominently ketamine and DMT). OBEs can be experimentally demonstrated are are thought to occur due to disturbance of the functionality of the vestibular system (cochlear)[2].
History
OBEs have been well-documented for centuries. One of the first recorded instances was a report from the French otologist Pierre Bonnier in 1905 which reported a patient "divided into two persons, one who had not changed posture and another new person on his right, looking somewhat outwardly. Then, the two somatic individuals approached each other, merged, and the vertigo disappeared."
Mechanism of Action
Whilst OBEs seem to pull consciousness fully from the body, a lesser form, of this seems to be depersonalization / derealisation. A suggested evolutionary rationale for this mechanism is that OBEs tend to occur pre or during traumatic events, suggesting OBEs are used almost as an ejector seat of consciousness to avoid long term effects of psychological trauma.
