duality of existence

His works consistently explore the duality between suburban normalcy and underlying darkness, reality and dream states, as seen in Mulholland Drive and Twin Peaks.

He deeply examines the duality of material and spiritual existence, consciousness and the physical world, through meditative philosophical narratives in films like Stalker and Mirror.

His filmography obsessively probes the duality of mind and body, sanity and madness, creation and destruction, particularly in The Fountain, Black Swan, and Requiem for a Dream.
