The book is divided into four parts covering topics such as sleep, the importance of sleep, the concept of dreaming, and the impact of sleeping pills on society. With 16 chapters plus a brief conclusion, the book's narrative is structured in a way that each chapter can be read independently without losing its significance. The author emphasizes the standalone nature of each chapter, suggesting that readers can explore them in any order. By focusing on discussing the general takeaways rather than delving deep into each chapter, the conversation aims to avoid getting lost in unnecessary details and provide a more enriching experience for the audience.
