Mine felt like girls hands, one on my forehead pushing down, one on my chest, then two more around my hands. They felt human. I tried screaming and no sound came out, just air. I tried digging my nails into her hands and she dug back. I tried wiggling out from under but I was firmly held there. The only thing that managed to free me was when I manoeuvred my hand in a circle managing to graze the side of my hand on the bed. Seems like that did it.
Through it I actually thought someone broke in the apartment and I was going to die. Now my hearts racing and I can't believe it actually happened. They're not kidding about sleep paralysis.
