CRAZY DREAMS !

Okay so i keep having these crazy ass dreams 9/10 involving my boyfriend cheating on me. I will wake up distraught, crying etc. its so real its hard to shake it. I keep asking for reassurance from my bf after these dreams and im sure he over it, or thinks i have a guilty conscience or something. PLEASEEE someone help me either STOP having these dreams or tell me how i can stop acting like its the REAL him thats been cheating when its my dream?? Im pregnant so it hurts me even more thinking he would do that to me right now & its really hurting me and stressing me out..
