Often when I'm getting dressed in the morning or having a bath at night, I discover a bright red scratch on my stomach or chest or upper legs, or a small bruise on my knee or elbow, but I have no idea how I done it. Some people say I must scratch myself in the night, but with nails as short and blunt as mine, they can't even scratch butter. And if I try scratching myself on purpose with my fingernails, I cannot do it at all, but when I find a random scratch it looks like I've walked through a prickly hedge. Also I have no idea how they get on my tummy or chest because usually they are covered with clothes. The other day I even found a really long, glowing red scratch right across my tummy, in the shape of a walking stick, and God knows how that got there. A few years ago I woke up and found my finger was bleeding, and there was a big scab that I was sure wasn't there the night before, and it took ages to heal up and I've still got the scar today. Surely I can't of done that in my sleep, I have no sharp objects in my room to make that sort of scratch on my finger, and it was in a place where nothing could really get to it (right between my index finger and middle finger).
Anyone else find scratches or bruises and have no idea where they come from? Do you know how they form like that?
