Haven't had horrible nightmares, but before my pregnancy i did not have dreams in general. Now i have them almost every night, and they are mostly uncomfortable,unpleasant. I guess that depends on the stress level - you are going through hard times. Try to drink warm tea, warm milk. Meditating might help also - even if you dont feel like doing it properly - try to sit down and breathe depely as often as you can, holding onto hope that everything is going to be alright.
I hate the nightmares I literally got up last night into my mums bed that's how scared I was . 36 weeks but I guess it's normal
Tea really helps to soothe. I just woke up from a nightmare. Its 3am here in Cali. I know how you feel ):
