I have had times of dissociation a lot in the past though not for years, but I realized that while running, particularly running these long distances I have, that I often dissociate. It's not psychosis since I can clearly distinguish reality. But I was going along, my app announced a mileage, and I honestly felt like I had run the whole last mile as if I were in a movie or maybe just stuck inside my head, paying no attention to the rest of my body at all.

What causes that? Stress? Trauma? Medication?

Things have been about as stressful as I can remember in recent times. Maybe it's that? I can at some point recognize the dissociation and when I do, I can make myself snap out of it. But it's been happening more & more lately. I suppose it's something to mention to the pdoc tomorrow, or is it just par for the course with bipolar?
