What has he done to regain your trust after acting like that?
What reason to you have inside to know he would never hurt you like that again?
It is human nature to feel at risk of a repeat hurt after an experience like that with someone. It sounds to me like you don't have confidence that he won't turn on you again and that fear is manifesting I your dreams. Has he done some very serious work to explain why it happened and why it could never happen again? Has he shown you that is not his true self with both words and deeds for an extended period of time? If not, that would have to happen in order for me to feel safe again.
Be gentle with yourself.
