What do you do in bed that's annoying?

I mean sleeping, not having sex. (but you can also include sexual related answers if you’re so inclined)

Say you’re sleeping with your partner, (or someone else, for whatever reason) what’s something annoying you do that drives them nuts?
Do you snore, fidget around a lot, talk in your sleep, drool all over the pillows? Do you read a bit in bed, or watch TV for a little bit, preventing your s/o to fall asleep?
I’ve been alone in my bed for quite a while, but my ex boyfriend got really annoyed that I always yanked and stole the covers. Classic, but it’s my annoying bed thing. Not hard for me to believe, because I always wake up buried in mounds of blankets, whether someone’s with me or not. You?

Feel free to say what your s/o does that annoys you when sleeping, too.
