The worst nightmares ever!!

So usually when I am pregnant I have those dreams where my husband is cheating on me. I think that's pretty typical of most women. I remember the first time I had one when I was pregnant with Adriann, I woke up and all day I was soooo mad at Akoni. He had no clue why and when I finally broke down crying and told him, he just laughed. It was kind of funny, but your emotions are so overloaded that I was still worked up about it even after I had woken up. Well now I would give anything for those dreams because I am having the worst nightmares ever! I wake up with a start and my body is frozen and I can't move for about 20 minutes. It is horrible!! I have no idea what to do or how to make them go away. I try to watch funny tv shows before I go to bed so that I have something good in my brain, but I still am having the same nightmare. And of course it is a really stupid nightmare about zombies, which I haven't even actually seen any of them yet, I am just wandering around an empty city with people and military guys looking for guns so that if the zombies do show up we can shoot them. But I am so terrified the entire time. Stupid huh? Any suggestions on how to make them go away?
