Wow, Elias and Kevin, thanks so much for posting about this! I've never come across anyone else who Really understands what I'm talking about!!
Since I was a child I've had periods of time where I've felt, what I called "detached" - like nothing is real. It used to happen a lot when I was a child and teenager, and I used to really fight to "snap out of it". I remember a particular incident while sitting in class in school, I got that "out of this world" feeling - like a dream, like nothing is real and you can do anything and it doesn't matter. I had an overwhelming urge to go up to the teacher and pull her hair - just to prove nothing's real!
Luckily I managed to resist the urge and snapped myself back to "reality".
I know it sounds psychotic
I went through various possible explanations for it. No-one else seemed to have the same thing. I thought at one stage that it was just dreaminess, then, at one point, as a teenager, I decided it was the devil trying to make me believe that nothing's real so I'd "do bad things" (there's that psychosis again!

) and then, as I grew older, I figured (as I still do) that it is almost "seeing behind the veil". It feels like seeing the fabric, seeing the Illusion. For a moment, I become aware of the reality outside of the physical world. It's very difficult to describe as you've said. One analogy is: when playing a virtual reality game you suspend disbelief so you can really feel like the game is real - this is like when you become aware of the game and that the character you're playing is just a character.... I think that's the closest I can get to the description.
Definitely a feeling of not being me. I feel, during these moments "Who am I, what am I..." It's almost like waking up as someone else and not knowing who.... combined with a feeling of "nothing's real" dream-like thing.
I used to snap out of it as soon as I could. Wow, an hour, Elias, I don't think I've ever had it last that long in one go!
For the last few years, I've allowed it to go on as long as possible - I'm very curious to find out what happens if I let it go on. But I seem to automatically pull myself back now. I think there's a small amount of fear there (I've just thought of adding that new module to my Platinum - that might be interesting

) - and, although it doesn't happen spontaneously as often as it used to when I was a child and teenager, I can now bring it on deliberately, simply by becoming really acutely aware of my surroundings and myself. (like you would on a movie set that's very convincing - when you start looking closer, you see that it's not real

)
It's SO great to hear you guys experience this as well - it was Wonderful reading your descriptions and identifying with them.
