violently sleeping

I don't know what the hell happened last night. I just set my alarm and realized that the top isn't on my clock anymore. It had a door thingy on it to protect the buttons. It was there last night! Maybe I furociously hit it when it disturbed my slumber. I also managed to scratch my nose last night. Again, I have no idea what I was doing, but a fierce scrape of the tip of my nose by my thumbnail awoke me in the middle of the night. I bled and I now have a scab.
