I think I bit myself in my sleep.
When I woke up yesterday I saw a fresh bruise on my forearm, still bleeding dramatically under my skin. It was an oval shape, rather like a bite. To the best of my knowledge, no other human or beast had been in the room with me during the night. If anyone had bitten me, it must have been me. Upon analysis I realized the wound was in a spot I could have, in fact, reached with my own fangs.
I can’t imagine what I was thinking. Did I dream I was a bad person and needed to be bitten in punishment? Was I a dog chasing after a stick or child? Or did I suspect my arm was an invader from which I needed to protect myself?
