I think there are quite many "versions" of dissociation... The most "obvious" one is when someone loses time, e.g. goes by by bus and misses the bus stop or suddenly realizes that is in a place but doesn't remember how to they got there. Like they separate from the body, they might not here other people, they might think that are somewhere else etc... I do not fulfill these criteria but according to my T I am still dissociating a lot because:
- I am chronic (maladaptive) daydreamer
- I have problems with focusing, if someone is talking too long (which might be even 3 minutes) I stop listening,
- in stressful situations I am calm as I pretend that I'm somewhere else, that nothing can happen to me,
- sometimes when my T is saying something disturbing, the room starts spinning and I have to remind myself where I am and that I am supposed to listen... etc...

For instance there is no excisting diagnosis like c-PTSD which is actually the only one which I would get if it existed. For this reason if I needed any for the insuranse, I would either get PTSD but I don't fulfill all criteria, or my T would prefer DDNOS - Dissociative Disorder Not Otherwise Specified...
