Okay so last night I had a sex dream about having a threesome with my husband and his friend ( who not only I don't like, long story short I was raped my husbands mom told my husband best friend out of drunken rage and his best friend yelled at me and called me a liar in front of his entire family) so I'm not totally fond of this guy. Anyways I very much enjoyed the dream but i am against threesomes at one point in the dream it was just me my husbands best friend. After I woke up I felt really guilty and conflicted so o told my husband I had this dream ( I've had weird dreams like this my last pregnancy just not about his friend) 

Now I feel terrible and every time we have had sex I keep thinking about it.

My question is, Is it normal to be like turned on about the thought of that and like want to do it? I feel dirty and like I cheated. I don't even like this guy really and I don't know I'm just super uncomfortable. 

Kinda embarrassed so I'm posting this anonymously...
