Something that's been bugging me for a while, which I only started thinking about seriously over the past year or so, as prior to that it was just "something that I did".
When I was a child, and I mean since I can pretty much remember, so young, I used to do this thing to myself when I would induce what I can only describe as a state of disassociation. I achieved it by repeating to myself the words "I can't believe I'm here, I can't believe I'm here" over and over again until I was taken over by the intense feeling of not being present in my surroundings - I suppose I can explain it as like the real world was a movie which I didn't feature in. In hindsight it was a very bizarre thing to do, and I did it often as a child.
I can still induce the same feeling on demand, but it scares me now, so I don't.
Has anyone else done this? Come across anyone who did or does this?
