Don't be rude...

Ok so I know this might sound crazy, but I've had 2 dreams of me cheating on my bf and idk why. I know some people don't think anything of dreams, and some people do, but this is actually worrying me. I'd never do anything to hurt him, I love him but why am I having these dreams??? Plz don't be rude I'm just worried and wanna hear some other people's opinions.
