Everything you ever wanted to know about your nightlife. Whether it's a flight, naked, nightmare, or exam dream, whether it's erotic or prophetic - Douwe Draaisma knows them all. He also shares the exciting stories, analyses, and interpretations from dream researchers, psychologists, and neurologists. Some parts of our brain must remain awake while we sleep. They start weaving strange tales: an exam that needs to be retaken, one that was passed years ago. You meet people who are no longer alive. Suddenly, you find yourself naked among colleagues who are completely unfazed by it. Or you jump from a steep cliff and can fly like an eagle. Many of these stories dissolve into thin air upon waking and are quickly forgotten. However, they often raise questions and linger in your mind for days: Why must one always go through exams in dreams?.
