Dreaming about my abuse

It's quite weird honestly. I haven't got specifically a nightmare but just recurrent dreams about different situations regarding the aftermath of my abuse. It's been already a month and I lost contact with all of them almost a month ago, but since day one. When I dream it's only stuff abused related. Sometimes I get a couple of awful headaches and stomach issues (not covid, already got tested).
I assume there's no way to stop the nightmares, but how do you do to cope with all the physical pain regarding it
