I got the DID dx, I look for this kind of like the second poster making sure that the disruptions and discontinuity in a conversation don't happen. I share this from an alter level. If alters are I called it amen corner then it like a revolving we are associating to the conversation listening but also input so that they know we are with them.

If you read dissociation and how everyone wonders especially while driving that should clear it up some.

If you are talking in therapy on one topic say for instance baseball it should be about all things baseball. I'm assuming the poster is not diagnosed but just wants to know what is dissociation. It should be about(connects) when you played, what it was like, what was the teams about etc, I don't think you need to remember everything.

If you start to get sense of self problems in your environment that indicates any plurality happening then you it will show itself soon enough. That would be indicative of disordered dissociation into derealization depersonalization etc ptsd the spectrum, until an alter can show itself for what it takes where you attend for the diagnoses if that is what you are requiring.
