If you don't have it out by now, I'd say its probably to just water. Its an earwig most likely (an insect, do a search). They like to crawl in people's ears, usually while the host is sleeping, but because they like moist areas, they sometimes hide in faucets and shower nozzles. Better get it out, or it will lay eggs in there.

I was just kidding, of course. Earwigs don't really go in your ear. They mostly just hang around in my woodpile, looking gross. Sorry. Hope you got the water out.
