Let me explain what just happened in my mind (i know, dreams are boring but this is a condition which makes it cooler.)
so im lying in bed, as you are when you sleep. but sleep paralysis strikes between dreaming and waking so you will often end up in your own room. And as you may have guessed I couldn't move at all. I could see a face at my door but i couldn't tell if they were going to help me or kill me... as your still kind of dreaming you still have that sleep logic working against you, and for some reason people normally feel a kind of pure terror when in this state.
well i admit, i was trying to shout to them, and a shout where you cant move your mouth is an uneartly sound let me tell you, especially when it is the only thing you can do. after shouting for a couple of minutes i stopped and i think i came back to my senses at that point.
And back to sleep for me. Good night.
