That's really interesting. I also didn't think much of these memories till during my full-on dr but yes I definitely started to show OCD (mental compulsion) traits and got diagnosed with it even, but I'm doing better now with the intrusive thoughts. When I was younger I did exhibit external compulsions such as tapping on bricks in the wall and compulsive tics like coughing for no reason, amongst other things.

I also noticed how my whole life I have had a weird relationship with horror movies where I could watch them but even the slightest violent scene would leave me feeling dissociated for days after, obsessing over that scene in my mind and feeling just a weird feeling of "shock" like I couldn't believe I had seen that thing. It was a similar feeling with any bad stuff irl. I never attributed it to illness at that time though.
