This might not be DID at all.... It could be so so many various things--
it could be a symptom of
Borderline Personality disorder(identity struggles and also they can tend to change to be like whoever they are around or are influenced by at the moment), it could be that you are young and trying out different things to "feel" how it is to be that kind of self. (I know you said it didn't feel like that-- but-- I wouldn't totally eliminate that possibility).

Or-- If you want to think "way out", like I do-- it could be some flashes of past lives. I have had those.

I think you should seek a professional for advice and not take us for our word -- -- as we don't "see" you and aren't supposed to diagnose here, and also, most of us aren't psych-professionals.

Wishing you helpful findings in your search.
