One morning, I was dreaming fully unconsciously, I went into a classroom, lied on a desk, and immediately, my eyes closed and I couldn't move (in the dream). I think I was able to feel my bed (not sure). I remember feeling the difficulty in moving. I was still not aware I was dreaming. I thought I was awake, but then I woke up.

Another morning, I had another dream like this, but instead in a bed room. I could feel the bed, when I tried to move, I was unable. I even tried to shout. I was not to do that either. I then woke up. I know that I was dreaming, and I was not just normally awake and in paralysis (what normally happens), because in this dream, I slept with my head at the "top" part of the bed, and when I woke up (or got out of paralysis), my head was at the "bottom" part of the bed. It only seemed real.

Can anyone explain this?
