Paul testified that whether in the body, or out of the body, he couldn’t tell. Yet he certainly had visions.
The near death experiences commonly talked about, often refer to separation from the body. Oxygen depletion causes hypoxia and euphoria (sense of well being). I won’t deny people have experienced visions, but you are not dead.....until the blood is ‘dead’. When the blood is dead, the damage to the rest of the body is irreversible, imo.
