The mind at night : the new science of how and why we dream / Andrea Rock.

Psychologists and philosophers have long grappled with the mysteries of dreaming, and now--thanks largely to recent innovations in brain imaging--neuroscientists are starting to join the conversation. In this book, the author traces the history of this emerging field. She then takes us into modern sleep labs across the country, asking the questions that intrigue us all: Why do we remember only a fraction of our dreams? Why are dreams usually accompanied by intense emotions? Can dreams truly spark creative thought or help solve problems? Are the universal dream interpretations of Freud and Jung valid?--From publisher description.
