Cheating dreams.

Lately I’ve been having dreams that my bf is cheating on me. My bf and Have been together for almost 2 years. At the beginning of the relationship I used to have these dreams all the time. But then it stopped. But this last week I been having them and I wake up sweating and feeling sad/mad. I don’t have a reason to suspect my bf of cheating so idk why I’m having these dreams. Maybe it’s because there’s been a lot of drama with the people around me involving cheating? Idk I just hate having these dreams because I start to question my trust for my bf.
