Well, I'm schizoaffective & I experience a lot of depersonalisation/derealisation. I wouldn't go on to say that it would be a disorder in or of itself. But I think it has to do a lot with the psychosis. Like a subtle break in reality in order to cope with stress? But that's just my experience.

I got a 46! But the questions about being cut off from my emotions, feeling out of control, & whatnot really apply to my other dx's so I'm not sure just how much it has to do with dissociation.
