There have been times when I go to sleep that, between the time of consciousness and full sleep, I seem to doze into a daydream type setting. I'm usually walking around in nothingness, and its so stark that I never remember whats going on when I wake up fully again.
The point to this is that I always seem to trip over something, and right as I fall I shoot back to reality, and it feels as if my body falls from 2 inches above my bed. Its an odd experience, but it has occured rarely throughout my life and I've never thought much about it until now.

The whole 'thudding' onto my bed is very akward, and it always happens when I literally trip over something in the 'daydream' I have. So what goes on here? I'm not sure if others experience much either, but It'd be good to know about.

Answers to this would be very much appreciated, and I thank you for your time.
