This book is a reissue of the novel Le Sixième Sommeil (“The Sixth Sleep”) by Bernard Werber, made as part of a school project at ESADHaR.

The main character, Jacques Klein, evolves within an intrigue deeply linked to the world of dreams. His mother, a sleep doctor, and his father, a navigator, invite him at different stages of his life to become aware of the importance of dreams and the possibility of traveling in deeper and deeper phases of sleep.

Playing on the blue of the seas explored by Jacques while echoing the work of another Klein, the color blue occupies a special place in this reissue. The iconography is made up of photographic compositions created according to the principle of cymatics. This neologism designates a technique for visualizing acoustic vibrations. It echoes the resonance frequencies of the brain that vary according to the different stages of sleep.
