“Beethoven and Paul McCartney cited dreams as the spark behind some of their musical compositions (including McCartney’s famous “Yesterday”). Some of the most recognizable sequences in film—sections of Ingmar Bergman’s Wild Strawberries, Fellini’s 8 ½, Richard Linklater’s Waking Life—are translations of the directors’ dreams. Mary Shelley credited dreams with inspiring Frankenstein; E. B. White with Stuart Little.”
