“Dreams are messages from the deep” is a significant quote from Denis Villeneuve’s 2021 film Dune, acting as an enigmatic opening line hinting at prophetic visions, subconscious revelations, and the profound influence of the “deep” (subconscious, desert, cosmos) on characters, particularly Paul Atreides, setting a tone of mystery and psychic depth central to the Dune universe’s themes of destiny and altered states.
