My roommate and I were sleeping on our respective beds. All of a sudden I woke up on my side, facing my roommate and I was calling out to her. However, when I opened my mouth nothing was coming out. I kept screaming her name but nothing was happening and I couldn't even move my body. A couple seconds later, I realized that I could move a little and was trying to get up, but started to fall off my bed, which is when I woke up.
