I have a couple of times. In 2001 or 2002, I woke up with my head at the foot end of the bed, and the rest of my body perpendicular to the bed. I have no idea what I was dreaming but I obviously got up, sort of. I had scraped my knee and thigh and bruised myself real good, and due to how I was lying, I ached. I felt completely disoriented.
The other time was in Jan or Feb 2002. I was sick (not sure if it was cold or flu) and had a fever. I was sleeping in my room with my door closed. I was dreaming that I was on a ship. IRL my mother came in and checked on my state of being. Upon leaving, she couldn’t get the door closed because a blanket had somewhat slid down on the floor, so she threw the end on the bed, over my legs. In my dream, to my horror, something grabbed my legs and pulled me down through the deck. I thought it was a tentacle monster (IDK if I meant octopus or squid, but tentacle monster was what the word I thought in my dream). I sort of woke up in time to see my mother close the door, only I didn’t see her, I just saw something leaving. Without thinking, I jumped up and opened the door in time to see her enter the bathroom, I still just saw something and thought of the tentacle monster and ran after her. I put my hand in the door as if I was wielding a weapon, and she said that I looked wild, at which point I woke up completely and noticed what I was doing and felt confused and embarrassed. IDK if the fever contributed. I have never taken that long to wake up before before.
A few times I have woken up to find myself unable to stop a movement, like putting my hand down (once that meant hurting my thumb against the commode next to the bed), but nothing too big.
