The out of body experience (OBE) is the experience of moving away from the body so it is difficult for the scientists to record these experiences easily and measure their results because they are subjective. As a result scientists can study these cases indirectly by examining records of people who have had an OBE. Out-of-body experiences were also recognized in Hindu philosophy, the “subtle body” referred to as the sukshma sharira was able to separate from the physical body under certain conditions.
The main characteristic of an OBE as described by Carlos Alvarado is the sensation of floating away from the body or becoming aware that the individual is at a distance from the body. Also the experiencer might feel another subtle body and gradual or immediate separation from the physical body, observe it from a distance and see a connection between the astral body and the physical body while being in sleep paralysis state which makes you unable to move.
