Sex dream about brother in law

I woke up today shocked. I had a sex dream about my brother in law. So random! I’ve never really been attracted to him. He’s not bad looking but that thought never crossed my mind. In my dream I knew well I knew I was married and what I was doing was wrong but I didn’t care. We would sneak off and make out and he would finger me but in the dream I hiding from my husband and he craved him I was the one mostly going after him. what the hell does this mean?! Also, I just remembered something for my birthday two years ago I got a glammed up right skimpy dress and invited both his brothers to come with us to a night club and when we went to pick them up said brother I had a dream about checked me out like when he saw me he looked at me up and down. Thats about it nothing else I’ve noticed. I don’t have any interaction with him and we aren’t close. He’s going to be my children’s godfather soon and yeah. Wtf.
