I levitated once as a child 6 or 7. I'm not sure how. I was about to wake my mother for work. As I leaned over to shake her my feet came out from under me and I hung there for a few seconds, stood back up and all was normal. It never happened again. Pretty weird. I wasn't under the influence of any drugs or anything. It just happened on it's own. Never told anyone about it 'till now.
