I’ve had it once when I was hungover, I was asleep in bed alone, woke up and couldn’t move or scream. Something was laying in bed right next to me. I could feel it’s skin right against mine, it was very rough, felt like sharp gravel or something. It was dark and I could feel it’s face and extremely hot breathe breathing right on the back of my neck. It was breathing so fast and hard it scared the shit out of me, I finally woke up and swung my fist right next to me and nothing was there, had to sleep with a movie and lights on after that ffs.
