Is it normal my OCD fear thoughts come back in my dreams/ REM sleep at night? It makes me even worse the next day...

Whenever anyone starts to feel like their thoughts are less triggering or they feel a moment of happiness/ relief OCD tells you that you want the thoughts back or you actually like having the thoughts and maybe thats just the person I really am? I feel like im going insane😢

I had a really bad nightmare revolving around one of my big themes and I woke up with the panic still left over the dream as if it was real and I kept thinking about the situations. I tried to tell myself it was just a dream, but then it made me question real life. So then it was a cycle of ruminating about the events as though they were real and my reality which really messed me up bc my biggest theme right now is becoming schizophrenic/catatonic/"crazy." I feel stuck in a loop, I've tried saying the "maybes" and even talking to my partner about other things but it just keeps looping in my head "am I crazy?" "I can't differentiate between dreams" "I feel like I'm stuck in my head and I can't even talk". Any tips? I feel like I'm at the crescendo of my 20 years (lifelong) ocd due to stress from moving soon.

I want to know if this an ocd thing because I haven't read about it when I started searching of the disorder to make sure I had it (that before my diagnosis) Does your thoughts get worsened when you are falling sleep or are half awake half sleep? I noticed mines would get intensified when I'm trying very hard to stay awake or when I'm close to falling asleep
