My girlfriend speaks in tongues. Occasionally she also comes out with gems in English, such as "Link won't do it... his sword won't let him," and then there was the time that she hit me, and said "NO." I was really worried until I found out she was asleep. And then, on a different occasion, with varying degrees of annoyance and worry... "No... let me do it... no, let me... no, no, no, no, no, no, no..." I sense a theme.
I don't know about what I do in my sleep so much (I'm a heavy sleeper) but I have been accused of coming out with some interesting things just before I fall asleep. The worst are the times when I catch myself doing it and then try and deny it.
"I don't get why the flowerpots are blue... and they have blue on the French flag."
"You know those stamps they give out with manga? I wish you could change them for kittens."
When I worked in WH Smiths I caught myself on the verge of offering my girlfriend a plastic bag nearly every week.
My brother once turned round in his sleep and whimpered "I can't do it... it's too small," to my continuing amusement.
The very best, however, is a mutual friend of myself and my girlfriend, who, chastely sharing a single bed with us one time (:P), rolled out one morning onto the floor, but didn't wake up. My girlfriend, being a kind person, decided to tell her, even though I tried to make her just go back to sleep (what? She was next to me. She was
warm).
"Hey. Katy. You fell out of bed."
"Nrrrgh?"
"You fell out of bed."
"No I didn't."
"Katy, you fell out of bed."
"What?" (Hurt and confused) "You
pushed me!"
