SLEEP is a linear time narrative about the different sleeping stages. To best describe the progression of sleep cycles, the chapters are portrayed by the sequential change of colors in the sky from dusk to dawn. Additionally, the pages of the book are numbered in an alternative manner; a visual system of clock indexes replaces numerical values. Thus, when flipping the pages time changes together with the phases of sleep.
The reading experience of the book becomes more effective, integrating the visual and kinesthetic, turning into a progression through time and space explained by perceivable elements: the color of the sky and a bedside table clock.
