Scratches on my arm when I wake up
I think I've had this issue for a very long time now. I would wake up to find scratch marks, sometimes rather long ones, on my arm or even my leg shortly after waking up. I don't have any pets and I never have, and I generally don't go out much either. Today I see 3 scratch lines parallel to each other on my left arm and I'm kinda freaking out.
IS IT REGULAR?
