Don't worry, you are totally normal. When I was pregnant with my son I had crazy sex dreams all the time! That didn't happen when I was pregnant with my daughter, though. I read an article about having sex dreams when you're pregnant, but I can't remember what it said about why it happens. The strangest part about the dreams I had were almost all the encounters where with women and I'm straight! But it happens, so I wouldn't worry. Many women have a fantastic sex drive, too, while they're pregnant. I was not one of them, though, and my sex drive when to nothing after my kids were born. But anyway, write your dreams down in a journal. It will be funny to go back and remember them later. I just had bizarre dreams altogether when I was pregnant, not just sex dreams.
