I Have Always Had Vivid Dreams With Repetitive Dreams

Lately ive been having these very vivid dreams about my ex husband. Well soon to be ex husband. Im back together with him but i have the feelings of knowing that nothing has changed and he'll abuse me again in my dreams, sometimes we're already fighting. He keeps saying how I just packed up and left and how dare I do that to him no resolve or nothing. Thats why I left in the first place. Its so weird though...im not thinking of him so why is he in my dreams.
