Does anyone else here have an issue with dissociation, especially depersonalization/derealization?

I have had this issue even before going on psych meds and also when I took meds that made my feelings completely numb.

Lately, it's been happening to me again, more and more. Especially when I'm running. It is like I just gets lost in my head and my body keeps running on without any thought from me. Then, my app will announce a time or mileage, and I will realize I've been lost up there for over 2 miles. Sometimes, it's a bit like watching a movie, but more, it's just like my body does one thing, my mind another.

This morning, I ran for a long time. When got back home, I realized I had spent at least half of my run completely dissociated.

I can always come back into my body from the dissociation if I choose to, though I guess lately I want to less & less?

Why now? What causes it? Is it part of bipolar? Does it just happen or have a trigger? Is it psychosis? There was one time I was psychotic and dissociated, but at that time I was confused as to if what was happening around me was reality or not. I just couldn't tell if what was happening was real. But these experiences lately, I have no confusion as to if what is going on around me is real or not?

I'll bring it up with the T tomorrow and the pdoc next week.

Does anyone else have this? It's scary it seems to be happening more & more. What if there is a time I don't choose to come back to reality? Can that happen?

Is there a way to treat this or not really?
