“A major discovery for Fellini after his Italian neorealism period (1950–1959) was the work of Carl Jung. After meeting Jungian psychoanalyst Dr. Ernst Bernhard in early 1960, he read Jung’s autobiography, Memories, Dreams, Reflections (1963) and experimented with LSD. Bernhard also recommended that Fellini consult the I Ching and keep a record of his dreams. What Fellini formerly accepted as “his extrasensory perceptions” were now interpreted as psychic manifestations of the unconscious. Bernhard’s focus on Jungian depth psychology proved to be the single greatest influence on Fellini’s mature style and marked the turning point in his work from neorealism to filmmaking that was “primarily oneiric”.”
