Sorry if i am posting this in wrong section.
During afternoon i was watching movie, i was in confortable position, tired and started to fall asleep. Soon i closed my eyes a bit and daydream started in my head about football game. During the daydream as i was kicking the ball my leg also moved(not too much but i lifted a bit in the air while laying in bed). I noticed this and then started to imagine myself kicking the ball again to make my leg move again but had no results.

This has happened to me before but i never bothered with it but now i am eager to find why my body reacts sometimes during those daydreams. Is not like i think of doing those movements or give any commands to my physical body in bed, it was more like watching a movie.

Funny to say, sometimes even full awake when watching a martial arts movie, when someone in the movie is about to get hit, my head also moves on its own to avoid it,like i am the one to receive the hit. But i am more interested with this daydreams during falling asleep when my body reacts
.
And why is soo hard for me to fall asleep in the morning on my back after WBTB for WILD and soo easy to fall asleep at afternoon nap?
