Those things Dragh says happen to me pretty often. I love to sleep, and I remember lots of the dreams I make.
Once when I was a kid something weird/funny a bit like that happened to me. I was sleeping on a mattress on the floor, beside my sister's bed in her room because there were works going on in mine. In my dream, I was in a kind of place like you see in old western movies, kind of arid & desertic landscape. I was laying (trying to sleep) under a kind of very low, sloping & proeminent rock making a bit like an awning over me, beside a campfire. Suddenly a humanoid creature's feet was sticking out from the top of the rock that I was under and was balancing in front of me, kicking me at times. I slammed it, punched it but the creature wouldn't take it off from there; so I bit it (!?!)... It's weird how much, in dreams, everything appears like normal... <img src="/ubbthreads/images/graemlins/rolleyes.gif" alt="" /> I don't remember anything of this dream after that, so I suppose that biting the feet worked to make the creature take it off from there...
On the day after, my sister discovered a bite mark (teeth shaped red marks) on her feet; she discovered it only by accident in the later day. No wonder how she got it, eh?
But the weird in all this (apart from making a such unusual dream) is that nothing of this had awaken any of us two, the biter neither the bitten! <img src="/ubbthreads/images/graemlins/delight.gif" alt="" />
