There was a period in my life during which, for some reason, I started experiencing sleep paralysis. One afternoon I woke up from a long nap and I couldn't move. I felt like I was literally going to die. It's a strange feeling and I'm not sure how I would describe it to someone who's never felt it. Try to imagine that someone is holding a gun to your head and could pull the trigger any moment. I didn't see or hear anything, but I could sense a presence, located somewhere above my head. Whatever it was, it was the source of my fear. It's like it was emanating this strong killing intent. I knew it wasn't real because I'd experienced sleep paralysis before, but even knowing that, it was overwhelming. As soon as I could move, I got up and ran out of the room.
