Sleep Paralysis
Anyone ever had it? Got reminded of it by all the threads about dreaming and shit. It's fucking terrifying. Wake up, can't move arms, can't speak, can't even open your damn eyes. It's a horrible experience. Only happened to me twice in my lifetime, unless you count that time I realized I was dreaming but couldn't wake myself up and just started struggling (which made it so I couldn't even move in the dream), then three.
Had it a couple of times. Kinda nerve racking but I've heard of that kinda thing before so I just relaxed and it went away.
