This also, but again not just when i'm asleep. I find scratches, bruises, sometimes even cuts and i'll have no recollection of where they came from. Sometimes I wake up with them, or sometimes like half way through the day or something i'll just find a few and in the strangest places too. I mean, i have nails but I don't scratch myself hard enough to break skin. My most concerning happenings are the nose bleeds i occasionally get in my sleep, i'll wake up and my face and my pillow will be covered in blood. Literally no idea why, because I really only get nose bleeds when i'm stressed out, which mostly only happens when i start over thinking about my existential issues. Not sure what could be stressing me out in my sleep, but it certainly can't be good.
