I've experienced sleep paralysis several times before when I was around 16 or so, but I'm currently going through a stage of extreme sleep deprivation where I can be awake for 3 days straight at a time, where even sleeping pills don't work anymore, and the sleep paralysis has become more common and more frightening. My earlier sleep paralysis experiences consisted of the paralysis, but no visions, but recently I have woken to a shadow sitting on the end of my bed, which then slowly turned round to face me, but I snapped out before I could see features etc. Then last night, I woke to see the light underneath the door being blocked out as if there was a figure standing outside my door. It has now gotten to the point where I no longer wish to sleep, as I find these experiences extremely terrifying. Several times I've gone to bed, promising myself not to panic if sleep paralysis occurs again, but each time it occurs, I can't help but struggle to regain control of my body and scream out, which takes about 20 seconds to achieve. What makes it so terrifying is the fact that my surroundings are exactly the same as they are when fully awake i.e the can of anti perspirant that I leave on my bedside table in real life will be there when experiencing sleep paralysis. I can't go on like this.
