Dissociation is a continuum. And within DID there is a continuum as well. I'm closer to what you describe, sort of co-conciosness, where I feel like I'm looking into the world through the filter of someone else's emotions and thoughts.
Tonight I had a few moments where there were all sorts of thoughts going around my head and none of them felt like my voice. I was lost in my own body.

So just because you don't have the same experience as you often see described as multiple, doesn't mean you aren't. Doesn't mean you are either.
