Deirdre Barrett

Deirdre Barrett, Ph.D. is an author and psychologist who teaches at Harvard Medical School. She is known for her research on dreams, hypnosis and imagery and has written on evolutionary psychology. Barrett is a Past President of The International Association for the Study of Dreams and of the American Psychological Association’s Div. 30, The Society for Psychological Hypnosis. She has written four books for the general public: The Pregnant Man and Other Cases From a Hypnotherapist's Couch (1998), The Committee of Sleep (2001), Waistland (2007), and Supernormal Stimuli (2010). She is the editor of four academic books: Trauma and Dreams (1996), The New Science of Dreaming (2007), "Hypnosis and Hypnotherapy" (2010), and "The Encyclopedia of Sleep and Dreams." (2012). She is Editor in Chief of the journal Dreaming: The Journal of the Association for the Study of Dreams and a Consulting Editor for Imagination, Cognition, and Personality and The International Journal for Clinical and Experimental Hypnosis.

Barrett is best known for her work on dreams and their contributions to creativity and objective problem solving. She interviewed modern artists and scientists about their use of their dreams, documenting dramatic anecdotes including Nobel Prizes and MacArthur 'genius grants' whose ideas originated in dreams. She also conducted research asking college students to incubate answers to real-life homework and other objective problems on which they were working, finding that in one week’s time, half had dreamed about their topic and half of those had a dream which provided an answer. Barrett describes dreaming as simply “thinking in different biochemical state” and believes we continue to work on all the same problems—personal and objective—in that state. Her research concludes that while anything—math, musical composition, business dilemmas—may get solved during dreaming, the two areas dreams are especially likely to help are 1) anything where vivid visualization contributes to the solution, whether in artistic design or invention of 3-D technological devices and 2) any problem where the solution lies in thinking outside the box—i.e. where the person is stuck because the conventional wisdom on how to approach the problem is wrong.
