Sharing a bed with someone who walks or talks in their sleep can be a disorienting experience. It's also, often, very, very funny. There are few things more entertaining than getting an unfiltered glimpse into your partner's subconscience. If you thought they were weird while they were awake, they're even weirder when they're asleep.

He farted very loudly and proceeded to say, “you got the wrong guy”
2.) From JWolf886:
My girl woke up one night and said "Did you find your rocks?" and I asked her what she was talking about and she said "I don't know, I'm just trying to make conversation." and promptly went back to sleep.
She has no recollection of this.
