um im not sure,but i wouldnt rule it out.
did you have anything else in your bed?

i have a ton of things on my bed. probably pencils which make it look like scratch marks. which would make sense because i used to do that all the time.

some people do scratch themselves in their sleep. i don't, but i know a few people who do.

I scratched myself in my sleep once, it was really quite bad and I still have a scar from it. So yes, you could have done it in your sleep.

I used to do it in my sleep not alot... but every now and then.... just as percousin i would clip your nails realy short or at least round them off so there not sharp :)

it is very possible because it has happened to me on more than one occasion. I used to cut in my sleep because i had problems with insomnia and sleep walking. recently, i've been having dreams of getting in fights and a few days ago i woke up with a black eye. don't feel bad though because it was only your subconcious. i know you didn't purposly intend to do it. i hope you are feeling better. talk to me if u need to. peace.

Well, I scratch myself in my sleep all the time. I wake up with huge scratches all down my legs sometimes, so dont beat yourself up to much, maybe you were just scratching?

I've never done it in my sleep... But don't rule that out, like everyone else has said...

Me I actually will break apart a razor hide the blades in my eyeshadow or something like that and use them when needed...

I have so many scars on my arm... No where else, just my arm....

Is that stupid??? duh the whole thing is stupid right???
