I also thought of the theory... we live in a fake world, but it's only real within us. Our world is only real inside of us because we can feel it. Our souls are the only real thing, and if we can feel the world ( everything of it, the good, the bad, the decent, the catastrophic.. ) it is real, however, it is only within us. A lifeless body has no soul, and that body doesn't feel, it cannot feel the world, for that's not a "real person". Our souls belong to somewhere else.
