Odd.

I felt warm ooze on my leg, looking down to see what the hell was leaking on my leg, I see a rather large gash . I don't know where it came from...or how it happend.

This scares me just a tiny bit, being I'm alone in a house, and just waking up from off the couch.

Anyone else ever found odd scratches, scraps or cut that were not there before, but are now unknowingly?
