#1 New York Times bestselling, award-winning New Yorker cartoonist Roz Chast's new graphic narrative explores the surreal nighttime world inside her mind --- and untangles one of our most enduring human mysteries: dreams.

Ancient Greeks, modern seers, Freud, Jung, neurologists, poets, artists, shamans. Humanity has never ceased trying to decipher one of the strangest unexplained phenomena we all experience: dreaming. Now, in her new book, Roz Chast illustrates her own dream world, a place that is sometimes creepy but always hilarious, accompanied by an illustrated tour through “Dream-Theory Land” guided by insights from poets, philosophers and psychoanalysts alike.

Illuminating, surprising, funny and often profound, I MUST BE DREAMING explores Chast's newest subject of fascination --- and promises to make it yours, too.
