"It all comes in sleep. Things are often not as they appear, or as you remember. Instead, they are exactly as you imagine, and only that. Animals understand the world without words, while we create our experiences as stories. Our past and future are stories we tell in the present. But how often did you discover these stories weren't true, that you misremembered something, that your logical explanation was completely wrong, that someone had lied, that a certain outcome wasn't certain at all? Does believing a lie feel different from believing a truth? Does reality change? The world in your head is the world, and the Earth turns unnoticed. You may already have a strange memory of the time when you will read this book. Don't fear - you can always read the stories backwards, then everyone will be home again. But forwards will be more rewarding"--
