KEEP HAVING DREAMS ABOUT MY BOYFRIEND CHEATING!!!!

Okay.. NO I'm not pregnant, but I had a really crazy dream that my bf had an affair with one of my sisters.. than a couple nights later I had another dream that he cheated with two other women and I caught him twice! Than in my third dream which I had last night I had another dream where I caught him in bed with my oldest sister.. like what in the fuck?!?! Every time I woke up so pissed and didn't even want him to touch me.. than after I calmed down we talked about it but damn... this shits crazy. No he's never cheated and he's never given me a reason to believe he's even messed around. Any advice?!?
