This book is about the reasons people need sleep. It tells about how we need sleep to function everyday and that if we do not sleep enough we will be disoriented and not perform our daily activities well. It also explains rapid eye movement, brain waves, and our dreams while we are sleeping.

This book was rather boring to me. I think it was because it was a very basic informational book and did not tell me anything I didn't know already. However, I think this would be a good book for young children who haven't learned this information yet to read.

Before reading this story to my class I would ask them to write down a few reasons why they think we need sleep. Then after reading them the book we would discuss their answers to see how their answers compared to the book. I would have the class draw a picture of the most recent dream they had.
