In The Twenty-four Hour Mind , sleep scientist Rosalind Cartwright brings together decades of research into the bizarre sleep disorders known as parasomnias to propose a new theory of how the human mind works consistently throughout waking and sleeping hours. Examining the interactions between conscious and unconscious forms of thinking as they proceed throughout the cycles of sleeping, dreaming, and waking, Cartwright demystifies the inner workings of the human mind that trigger sleep problems, how researchers are working to control them, and how they can apply what they learn to further our understanding of the brain.
