I definitely am on the spectrum. I would say I have dissociative disorder not otherwise specified but do have parts as well as used to have severe depersonalization and derealization (now those are few and far between thankfully).

I have never had times where I had items I didn't remember buying or people who knew me when I didn't know them, etc. Never have 'woken' up in random places.

For me, I have experienced large chunks of very hazy time, lapses of memory, yet not full on black outs...but I spend a lot of time at home, so it has never affected me like it might if I had to function daily in the outside world.

Although, years ago my dissociation was very severe (high school) and in childhood as well, but I did not know until I got older that I even experienced it as a child.

I have always had other parts, heard voices, felt shifts inside and all that kind of stuff with that type of dissociation, but over the years things have gotten a lot more quiet and less chaotic with it. I do still have times that are confusing and throw me for a loop...it is strictly internal, not external, as in I don't do anything noticeable that would make a person clue in that I was dissociating. It can be mild where I feel blended with another part or severe to where I am somewhere in between in this blank darkness unable to move my body or talk.

So, there definitely is a spectrum of dissociative disorders as well as severity and everything in between.
