I always thought levitation was impossible till it happened to me.
I'd been working afternoon shift and a friend dropped me at a railway station half way home. It was a deserted area, very quiet, and with 30 minutes to wait for the train I stretched out on a seat and dozed off.
I hadn't been drinking but my mind was still drowsy with sleep when I woke with the most peculiar floating sensation. It was then that I realised that I was floating almost a foot above the seat.
Alarmed, I looked around and realised that I was being held by the two biggest mosquitos I've ever seen in my life. God knows where they'd have taken me if I hadn't woken at that point.
Levitation! Yeah, don't knock it. I've been there.
