Journalist David K. Randall never gave sleep much thought -- until he began sleepwalking. Now Randall explores the research that is investigating those dark hours that make up nearly a third of our lives. This book is a tour of the often odd, sometimes disturbing, and always fascinating things that go on in the peculiar world of sleep. Taking readers from military battlefields to children's bedrooms, Dreamland shows that sleep isn't as simple as it seems.
