If when in dreams, and sometimes awake, there is a transcendent event like out of body experience, clearly it is not the body moving, so it is not the 'I' that is leaving the body, it is a transcendent soul experience. This transcendent soul experience, when finished and the body self-consciousness awakens/returns, the body 'I' has access to the memory and claims the experience for itself, such as "I left my body". It is not possible for the body to leave the body, so it must be a soul experience, and should be respected as such and not claimed to have been experienced by the body self, even though it has access to the detailed memory of the oob experience.
The same thing for dreams, the body never leaves the bed, the dream is an oob experience. Awake thinking state create Beta brain waves, Dream and other oob experiences are associated with Theta brain waves.
