I lost consciousness for a few seconds and woke up in a different plane of existence where everything and everyone (many beings all around me) was changing according to what I felt and thought. It was more vivid and real than real life. How can I now know that 'reality' is real if my mind can produce something superior? Both are perceptions of what your consciousness is dealing with. How do you tell which one is real? I think I might in minecraft a politician and see if reality breaks.
