We all dream, but what function do dreams serve? How can the examination of our dreams improve our wellbeing? And what, exactly, is going on in our brains while we dream?

This two-volume set examines dreams and dreaming from a variety of angles—biological, psychological, and sociocultural—in order to provide readers with a holistic introduction to this fascinating subject.

Whether good or bad and whether we remember them or not, each night every one of us dreams. But what biological or psychological function do dreams serve? What do these vivid images and strange storylines mean? How have psychologists, religions, and society at large interpreted dreams, and how can a closer examination of our dreams provide useful insights?

Dreams: Understanding Biology, Psychology, and Culture presents a holistic view of dreams and the dreaming experience that answers these and many other questions. Divided thematically, this two-volume book examines the complex and often misunderstood subject of dreaming through a variety of lenses. This collection is written by a large and diverse team of experts and edited by leading members of the International Association for the Study of Dreams (IASD) but remains an approachable and accessible introduction to this captivating topic for all readers.
