One of my worst dissociation events happened when I got frustrated at my therapist. I think it has to do with PTSD from childhood abuse. I learned that whenever my father or sister got angry, that bad things were coming and I'd better hide. Anger was the worst emotion and was terrifying. As an adult (and child), I RARELY got angry. Maybe once every few years, only for a few seconds, and with barely any noticeable "angry" behaviors.

In therapy a few years ago, I had been trying to explain something to my T, and she wasn't getting it. I raised my voice and really stressed what I wanted her to understand. Me raising my voice is probably the equivalent to other people's normal talking voice. I had never done this before (especially to someone I cared about so much), and was fully dissociated by the end of my short sentence. Not DID dissociation, but detaching from the world dissociation (couldn't make out the words being spoken to me, but was occasionally aware of sound occurring; couldn't process visual input; not aware of time passing; unable to speak; barely able to move - no blinking, could sometimes wiggle a finger, could eventually slowly turn my head even though eye gaze didn't go with it), and those are the only things I remember. I eventually came back and my therapist was sitting next to me on the couch with her arm around me. She had put a blanket on our laps, and I was resting my head on her shoulder. I think that's the only way I could have become grounded, and that's the only time in 3-4 years of therapy with her that she sat next to me. Too bad I couldn't hear anything that she was saying because I bet it was kind and supportive.

In short, yes. Frustration (my equivalence of anger) resulted in dissociation.
