Experimenting with Hyperfixations to Control Nightmares

since I've tried basically every therapy and it hasn't worked, I'm deciding to experiment a little bit. I know that as my maladaptive daydreaming decreases, the frequency and severity of my nightmares increases. therefore, I'm getting back into old hyperfixations that I had as a wee autistic. so far it's working. no nightmares whatsoever. I might even get into another game that could help if I end up liking it. I think this is really interesting and I'm wondering if I should gather some data from others who have had the same experience as me. if we can instead learn to control our daydreaming and sort of microcose on it, maybe nightmares would cease. I know many others who have this condition are also very creative people, so i think art therapy and maybe role-playing games like dungeons and dragons would be useful. I'll keep yall updated on this but I would also love to hear your experiences!!
