I very rarely sleep without either nightmares or weird and disturbing dreams. Even when I take a nap for like 30 mins or less. I have C-PTSD though and I heard it's common for people who are suffering from it to have nightmares. Sometimes I have a sleep paralysis too and sometimes after I wake up it takes a while for me to figure out which one is reality which one is dream.

Ghosts, monsters, corpses and weird creatures are regular in my nightmares. While weird dreams often about in my dream I try to alter the reality by time traveling but always fail. I try to finish the unfinished story but never succeed.
