The out of body experience can be defined as a subtype of existential intelligence.

Out of body experiences (OBEs) are those curious, and usually brief experiences in which a person’s consciousness seems to depart from his or her body, enabling observation of the world from a point of view other than that of the physical body and by means other than those of the physical senses. Thus, an out-of-the-body experience can initially be defined as ‘an experience in which a person seems to perceive the world from a location outside his physical body’.

Some articles have questioned whether the experiences are of an hallucinatory nature or purely a function of biochemical processes that occur in the brain, and, at the other extreme, some have linked them with notions of the existence of an immortal soul and other ideas generally associated with religious interpretations of human existence. Most readers are intrigued by the thought of being able to have and control OBEs, and see them as a potentially interesting experience, though some smaller number of people taking part in discussions are interested in trying to figure out their nature and function and their possible implications for the understanding of what it means to be fully human.
