This is a book by Sean Coughlan. Its a book of facts and theories and experiments and beliefs about something very close to our heart. We either love indulging in it, or we hate it for being such a time-killer. Sleep. Yes, its a book about sleep and everything connected with sleep.

It contains interesting facts and theories and beliefs about sleep, beds, pillows, dreams, fantasies and fairy tales. It also mentions some experiments carried out based on scientific means to ascertain the meaning of dreams, sleep, etc. Though it is a book of facts, it is nicely woven together in question/answer form where every chapter is a question. Every chapter answers (or atleast tries to) answer the question while posing many more. The book starts out with the invention of a bed, how it evolved over the years, how the need for a pillow arose. It then moves on to sleep, the phases of sleep, and how you move on from one phase to the other. The book finally ends with the comparison between sleep and death.
There are a lot of studies being conducted in this area to find out how much sleep a person needs at a given time in his life. Though it is not predictable, there are some observations that can help one tune his/her sleeping hours to remain fresh by sleeping for the number of hours required by his/her body. Some observations reveal that those who need more sleep are mostly creative, reticent people. Einstein’s sleeping habit is peculiarly interesting. He required a lot of sleep in short spans. He usually slept with a pencil in his hand. When the pencil dropped, he used to wake up from his sleep, feeling fresh and refreshed to continue working.
There are some pretty amazing facts you would find in this book. I’m listing a few of them
- Did you know that there is a bed tester? Yes, like we have a software testing team that basically checks the quality of the code, there was a job previously that of a bed tester!
- Did you know that there was a movie called “Sleep” that just showed a person sleeping for the entire movie. Yes a person sleeping! Why? Because the director felt that sleeping will become obsolete at a later time and this movie would capture that phenomena (Yes, given our busy lifestyle, we hardly sleep eh?)
- How do dolphin’s sleep? The question arises because the dolphin needs to come to the surface to breathe. If the creature falls asleep, how will the brain control this activity? The answer is that for a dolphin, the brain takes turns in sleeping (resting). The left brain will sleep first while the right one controls movement to the surface to breathe. This is a natural system, its not man-made!
- There are many beliefs about dreams. It was believed earlier that dreams are some supernatural means of communicating with a person. Freud and Jung later proposed theories stating that dreams were mrely dependent on the fears, traumas of the person and that they were linked to the subconscious. Painters in those ages than also tried to depict dreams in their paintings. How would you depict a dream in a painting? Interesting question right!
- Towards the end, Sean also states the beliefs that sleep and death are twin brothers and how both are linked with each other.
All in all, its a wonderful read which will leave you with loads of questions about the human body. I for sure am going to delve deeper into dreams and their studies!
