What does it mean when I dream about the guy my friend likes?

So there’s this guy, and I dreamt that he was flirting with me, quite openly. He’s who my friend likes right now. In my dream, he’s literally close to me for most of the time. He looks at me as if he were REAAAALLY interested in me. But then in that dream, he was going out with another friend of mine (aside from the one who likes him), and people kept mistaking me for her. And he doesn’t do anythign about it, and smiles whenever it happens.

Anyway, I’ve only thought he was something around two months ago, and I’m not really that seriously into him, but I still think he’s cool. And now it makes me feel a bit guilty because my friend likes him, and I don’t want to seem as if I was being a whore, because I’m pretty sure I’m the prettiest in our group, and I don’t want them to think that I’m rubbing it in their face by stealing this guy.

I feel screwed, I like someone else. After this dream, I feel like I’m starting to think about this other guy, like I’m so shallow. D:
