Dreaming of cheating?

Ma

I keep having these awful dreams that I am cheating on my fiance with different people. In one, it was his childhood best friend, or one of his coworkers, my old teacher, a neighbor, etc.

I've NEVER been unfaithful and I would NEVER EVER EVER do something like that! Nor am I AT ALL interested in any of the others I am dreaming about.

What could this mean? My relationship with my SO is wonderful and I wouldn't change it for anything in the world. Am I just freaking myself out? Ugh!!!!!!!!!!
