Something crazy happened last night before sleep, paranormal or totally normal?

I wouldn't worry about it. Its nothing paranormal but its not normal either u might be having sleeping problems. But what happen to you is called sleep paralysis. When u sleep the body secretes a chemical paralyzing your body so that you wont sleep walk a chemical that some sleep walkers don't secrete normally. In sleep paralysis your unable to move and since you are half a sleep and half conscious therefore you see things as if you were dreaming. Usually it doesn't last long and you fall back asleep since there isn't not much you can do out of fear. You can look about it here http://en.wikipedia.org/wiki/Sleep_paralysis i know they say wikipedia is not always accurate but this information compared to my knowledge on this is pretty accurate.
