means you're thinking about it a lot. that's all. it could be an unresolved tension of some sorts. you might want to see him again, at some point, or for some reason. there are no specifics in dream interpretation.
what does it mean to dream about the same person every night?
it could be that you enjoyed hooking up with him, which stuck in your mind. it could be that you haven't had sex in a while, which is sticking out in your mind.
maybe you see him in school, so you see him in your dreams.
maybe since you're bothered about seeing him in your dreams, he comes in your dreams more often!
any ideas of your own?
