Dr. Seuss's Sleep Book

Dr. Seuss's Sleep Book, commonly referred to as The Sleep Book, is a children's book written by Dr. Seuss in 1962. The story centers on the activity of sleep as readers follow the journey of many different characters preparing to slip into a deep slumber. This book documents the different sleeping activities that some of the creatures join in on: Jo and Mo Redd-Zoff participate in competitive sleep talking and a group “near Finnigan Fen” enjoys group sleepwalking. It opens with a small bug, named Van Vleck, yawning. This single yawn sets off a chain reaction, effectively putting “ninety-nine zillion nine trillion and two” creatures to sleep.
