Oh my gosh, I've experienced something similar to this. It happened on a night in which I was having trouble sleeping. I was shuffling around in my bed and trying to find my sleep. I fella sleep and awoke shortly after, but I was (or felt like I was levitating). My legs felt like they were being pulled upwards, while my head and torso being pushed into my pillow. Then after some struggling, I was pushed forcefully down into my bed, and I couldn't move my head. Like I felt a force pushing my head into my bed, I couldn't breathe. I can't remember the transition(which is what makes me think/hope it was a dream) but then I awoke and my tv was turned on, with only static playing. Creepiest night of my life.
