I am having wierd dreams about women i never met.?

I keep having this recurring dream about going to either a party or a club and meeting women I think Ive never seen before.well anyways were talking having a drink Most of the time were just getting to know each other and sometimes we get close and I kissed a girl in two of these dreams. these dreams never lead to or heavy rubbing (im not complaining). I am in a relationship (faithfully) and I guess I dont even cheat in my dreams but I just dont understand why I have these dreams and so often. I dont watch alot of tv and if I do watch its not too often.these dreams are innocent to me and I dont know why i have them.
