Dream about kissing my friend??

I have a boyfriend and he's amazing. I love him and he's the love of my life and we have no issues ! Last night I had a dream I kissed our mutual guy friend and it's freaking me out. I have no idea why I had this dream and I would never cheat on my boyfriend!! Idk what this means, I absolutely have no feelings for the other guy and we only hangout with him once a week. The other guy and I use to have a thing a year ago but that's way over and he also has a gf as well.
