I've been pregnant 4 times and every time I would have long and vivid dreams every night near the end. Pregnancy often makes you dream more and much more vividly than usual. I don't think your dreams are about what going to happen but what you want or expect or are afraid to happen. One way to put it is "It's your minds way of working out it's issues."
In my last pregnancy is when I had the most dreams about the baby. I had a few about her comming early and in several I would leave my hospital room, where my baby was, and either not be able to get back or would come back to the wrong room.
