Dreams about boyfriend cheating?

Hi ladies! So this is kinda weird but, for about a month now I've been having constant dreams about my boyfriend cheating on me. Like every night! And it's always different! Like one dream will be me catching him having sex with someone.. another will be me catching him sexting some girl and jacking off to it. I'm not sure why I'm having these dreams! I know for a fact my boyfriend would never cheat and he's the most loyal guy I've ever been with! He's in love with me and I'm in love with him. What could be the cause of me having these dreams?
