I had a dream about another guy....

So last night I had a dream about this guy I work with. Problem is, I have a boyfriend. I mean of course I like the guy. He's adorable and funny, but so is my boyfriend. Could this mean anything? In the dream he kissed me, then it turned into a nightmare because it started getting sexual. As soon as I seen his junk, I ran and then woke up. 😂
Its funny now, but I can't look at him the same because of it. Any advice on what it means? Also, any advice on how to stop the crush?
