It depends on what that woman represents to you. It's not anything to really worry about; it's not cheating or anything like that.
i agree with bukoden you cant control what you dream..its not like we have a button attached to us and before we go to sleep press the button of which dream we will have that night....god how good would it be to have that though....
u enjoys less with your wife.
What man doesn't dream about another woman while having sex with their wife? I'm not trying to be mean, but come on. Let's be honest lol.
in my opinion, it means nothing
you do not control what your dreams are about(normally) and are not willingly choosing to dream about having sex with someone other than your wife
