It could be many things. It could be just normal. it could be DID. It could be the way others have talked to you, which you might of subconciously not knowing it picked it up too. But as far as I know, I have never personally met someone who talks of thinking in the plural form who didn't have DID. But I dont know too much in that diagnoses either, and i try to keep it that way because of all the suggestiveness i've heard about it. And I dont need any added issues.. lol...
