Is this dream i had normal?

I had a dream that I almost had sex with my cousin's boyfriend. In the dream, I was kissing his thighs upward toward his crotch. We never did anything else though. I had just seen him the night before, we were at a party. I don't like him in that way at all. Is it normal to have dreams like this? Is it bad that I had this dream? Have you ever had a dream similar to this?
