I dont think it's that uncommon. I dream about it sometimes. For me, it tends to be after I resisted really bad urges and sleep right after that. Or just if I'm thinking about it a lot before bed. I don't know if that's the case with you, but if it is, maybe try to focus on other things before you let yourself fall asleep, no matter how tired you are. After really bad urges, I try to stay up another hour talking to a friend about random things.
