The dissociative disorders exist on a continuum with DID at one extreme end of it and the screening tests are more for all sorts of dissociative symptoms and don't differentiate between DID and nonDID. I hope that reassures you that it doesn't mean you have DID but does indicate you experience some form of dissociation. I have DID and my experience of my different parts is very different to what you describe. But that doesn't mean that you don't have DID! What you describe definitely sounds like it may be a kind of dissociation though and would warrant formal assessment especially if you have a history of trauma.
