When some people hear about fantasy worlds and the people who enjoy them, they often think that those people are not “rooted in reality”. The truth is that none of us are. We only experience mental models of what is real. Our experiences are just a infantile attempt to interpret a small percentage of what the universe is throwing at us. Magicians seem to have supernatural powers because they can break these mental models easily. You do not have a grip on reality. You have a sloppy thrown together system of models upon which you base your perception, but you don’t experience reality as it truly is. A real “reality check” would show you just how small and flimsy your grip on reality is. Keep true to your mental models of the world, but don’t be thrown into insanity when someone smashes them with impossible ideas.
