I am an artist, and a storyteller. I have this whole world in my head that for me is where I go when I just want to not be wherever I am.

People at work who are like browsing Facebook, reading a book between calls, chatting or whatever will sometimes ask me if I am ok, when I am staring at my screen (through it). Usually I get annoyed they interrupted my story building.

Never blacked out though! Sounds pretty scary. I do have a parent who went through a severe prolonged period of dissociation though, almost catatonic.
