Having terrible dreams....

I'm 34w3d and for the past week now I've been having the most realistic, awful dreams. Most are of me going into labor and something happening to my baby. Either she won't make it, or she gets sick. I've had a handful of my boyfriend leaving me and her, (which he'd NEVER do). But most are of her passing away, I hate even thinking about it or talking about it because it seems so messed up... It breaks my heart that I'm having dreams like these. I'm one of the most paranoid and anxious people ever and I can't help but fear of its a sign that something bad may happen.. I wake up unable to go back to sleep or crying. Relieved it was just a dream.. Literally this has been happening the past 3 nights in a row now.. I just want them to stop. I can't even sleep anymore. Along with getting up to pee literally, no hesitation, 2 times an hour every hour; and not being able to sleep comfortably at all, I'm so sick of these nightmares. Someone please give me some support to calm me down and reassure me all is ok. Has this happened to anyone else ? It's really taking a toll on me mentally.
