I (f20) keeping having dreams about boyfriend (m20) and his friend (m20)

I keep waking up thinking about them being together romantically—dating, kissing, and all that. I haven’t seen this friend in almost two months, but ever since he left, I’ve been having dreams about the two of them. It’s weird because I don’t think either of them are bi, so I doubt anything like that would ever actually happen.

He’s coming back for the holidays and staying with us, and I already know I won’t say anything to them about it, but I’m not sure how to handle the situation. I think his friend might be attracted to me, though, because he was kind of cuddling with us during his last stay. He joined the Navy, but I don’t really know too much about him.

TL;DR: I have a crush on my boyfriend and his friend, and I need advice on how to deal with it so they don’t find out.
