sleep drunking 

- verb - Similar to sleep walking; essentially, sleep drunking involves waking from a passed out state, walking around, speaking, peeing, or doing almost anything disruptive, and then returning to a passed out condition for the remainder of the night (or day)

Remember that guy that I let crash in my room last night? Yeah, he got up at about 4 and starting banging around, mumbling crazy stuff, and then he started peeing in my closet!! He doesn't remember any of that this morning. He was totally sleep drunking.
