i used to have dreams when i was younger about lying in bed, on my stomach, and this giant hand with a green colored aura around it would come down out of the ceiling and pick me up by the back of my shirt collar and pull me up towards the ceiling. i would yell for my mom, and it would drop me back onto my bed, then i'd wake up. i also learned how to control dreams like this. while i was dreaming...alot of the time, i KNEW i was dreaming... (it was still SCARY ass shit) ..but i would just drop to the ground wherever i was and close my eyes and count to 5. then i'd wake up. that's just how i handled them.
