We understand consciousness as the subjective experience the "How is it..." to perceive a scene, recognize a face, hear a sound, or reflect on the experience itself¹. It can be considered as a dynamic process and it can be temporarily divided in states². The states of consciousness depend on the subjective experience and the associated neurobiological correlates, and they can be divided in physiological, pathological or altered states². The OBEs are an altered state of consciousness, defined as the experience in which the observer perceives the world from a point of view outside of his physical body³. OBEs reflect an alteration in the multisensory association cortexes with the parieto-temporal junction (TPJ) playing a fundamental role⁴, ⁵. These experiences can occur during sleep paralysis². Sleep paralysis is caused by an intrusion of Rapid Eye Movement sleep (REM) intowakefulness⁶. It is a state, during waking up or falling asleep, in which a person is aware but unable to move or speak. It can be accompanied by the sense of a presence, auditory and visual hallucinations and in some cases OBEs⁴. OBEs during sleep paralysis can occur spontaneously, or they can be induced by training⁷. Here, we conducted an interview with subjects who had spontaneous OBE during sleep paralysis (S-OBE) and subjects who apply techniquesto induce it (I-OBEs).
