Richard Seddon and Dr Jean Brown use Rudolf Steiner’s ideas to explore the subject of sleep as both a spiritual and scientific phenomenon. In the words of the authors, this study is the first attempt to describe in anthroposophical terms the process of bodily restoration - and relate it to the basic scientific concept of rapid eye movements . Here, the authors explore the 4 stages of sleep, as well as dreaming and waking, in order to create a complete picture of the journey that happens every time we fall asleep. This book also details the human history of sleep, and how our conception of sleep has changed over time.
