Adding onto the other replys. You could be experiencing emotional flashbacks. In my experience it is almost like a inner critic or tormentor is able to transfer from person to person in my head. sounds awful, it's almost like I'll do everything to make it happen in reality (with my thoughts and behavior) at the same time experiencing brain fog.

Here's a nice description: Emotional Flashbacks are the least known and understood type of flashback, and yet the type complex trauma survivors can experience the most. These are where emotions from the past are triggered. Often the survivor does not understand these intense emotions are flashbacks, and it appears the survivor is being irrationally emotional. When I learned about emotional flashbacks, it was a huge lightbulb moment of finally understanding why I have intense emotions, when they do not reflect the issue occurring now, but are in fact emotions felt during the trauma, being triggered. But, there is no visual of the trauma – as with visual flashbacks. So, it takes a lot of work to start to understand when experiencing an emotional flashback.
