I can pretty much figure out my dreams, but this has been happening to me for the last few nights.

This is so hard to explain. I wake up and my identity has changed into something menacing and the real me is gone out of me. I have to really force myself awake to get my actually self to return to my body. I read online that it may be a form of dissociation. I have C-PTSD so that would make sense for me.

It's very disturbing. Does anyone understand this or had this happen to them?
