The only thing I know is my out-of-body experience, where I could look at myself sitting in a chair and then {walk?\drift?} out of the room and into another, watching the people in that room. Having no physical ability (it's still in the chair) but also no physical restrictions. Or, was it all hallucination?

Out of Body Experience induced

But, according to recent work by neuroscientists, delivering mild electric current to specific spots in the brain can induce them. In one woman, for example, a zap to a brain region called the angular gyrus resulted in a sensation that she was hanging from the ceiling, looking down at her body. In another woman, electrical current delivered to the angular gyrus produced an uncanny feeling that someone was behind her, intent on interfering with her actions.
