i am sick of these vivid dreams!

tw: i have ptsd and anxiety, since ive gotten pregnant i have such vivid dreams and most of them wake me up with awful anxiety or even a full blown panic attack. i have two other children and i cant keep waking up like this, does anyone know of anything i can do? i know you really can’t control dreams but if there’s any advice out there that ive never heard i would really appreciate the help
