Elli, I had night terrors for years, where I would wake up screaming and sweating and fall back asleep and have the same dream again. It drove me crazy. Some nights I would only get 2 or 3 hours sleep.
I tried staying up until I was really tired, I tried listening to calming music and reading calming words before I went to bed, I tried everything I knew to make it stop.
It took time, but eventually those dreams stopped. Like Dolly, I spoke to my dreams and told them to go away that I wasn't going to be afraid of them (it sounds strange but this was recommended to me and actually worked).
I think these dreams are a form of post traumatic stress and dealing with them the same way as we deal with PTSD often helps. There is a forum here called "Insomnia/Nightmares" and maybe reading through that might help.
Hugs
