i keep dreaming of being with my ex is it bad? should i feel ashamed even though i cant controll it?

Sigmund Freud had a theory that what you dream of is your subconcious trying to tell you something.  As a psychology major, I partly believe in this.I've read that if you dream of someone who's from your past, like an ex, it could be a sign of 'unfinished business' or the subject needing some kind of closure in a sense.  Do you still see him/talk to him?  Maybe he heard through the grapevine that you're pregnant?  There's really not much you can do about your dreams, even though you might feel bad about it.  I personally wouldn't tell my husband about it, because in reality, if he told me he was dreaming about someone else, it would really bother me!
