Where do you dig up all those tests
Hah, this one was actually on the INFP forum I go to. I guess that shows how similar in some ways introverts can be, including suffering depersonalization. By the way, they all scored really high.
I scored 21 for my past depersonalization, but I'm rarely depersonalized anymore, and only under stress. I have a fear of going back there again, but I actually think that keeps it away.
The one thing that was terrifying for me was that I really had difficulty telling dream from reality, a problem exacerbated by the fact I have really realistic dreams.
