I've had times like that. I don't know that it is related to the DID though. I'm intergrated and I still have times when that happens. Usually it happens in times of high stress. Maybe it is a way for our brains to try and deal with the stress, or at least my brain. Trying to put everything into nice neat catagories and working over time to do it under extra stress and it just overloads the sensory systems? I don't know, but I know my brain has done some pretty wonderful stuff for me. So I try to not let myself get to freaked out about this any more. I've talked to my T about this a lot because I used to let it freak me out, I'd think everything was going south again. Now I just thank my brain for working hard and try to do extra meditative and relaxing things to de-stress. Positive visualization, baths, the zen of nothingness, use aroma therapy before sleep.
