House Centipede. Not truly a Centipede but that's what alot of people call them. They crawl into your skin and lay eggs in your brain. I hope they didn't get you already. Usually when you see 1 that means there are about 200.
Completely Harmless if you leave them alone. They can bite though. We had them in the ministry houses I used to live in in college. I had one for a pet for about a day. Then it died. Contrary to the MIB movie, Bugs don't like Sugar water.
