"If I see a tree, I don't just see the tree; I qualify the tree, I describe the tree, I have an opinion about the tree. I like the tree or I don't like the tree. I may feel that the tree is beautiful or not, but my point of view, my opinion about the tree, is a story of my own creation. Once I interpret, qualify, or judge what I perceive, it is no longer real; it is a virtual world. This is what the Toltec call dreaming. The Toltec believe that humans are living in a dream. You are dreaming your life in this moment. You live in the story that you create, and I live in the story that I create. Your story is your reality — a virtual reality that is only true for you, the one who creates it. Long ago, somebody said, "Every head is a world," and it's true. You live in your own world, and that world is so private. Nobody knows what you have in your world. Only you know, and sometimes even you don't know."
