According to the director's commentary this is a movie about different worlds. The dream world has blurry edges, or has images or people randomly mixed in, just like dreams. The Incubus world is green tinted. The storytellers world is gold tinted. The real world is clear. Storytellers and Incubi can enter the real world but can only interact with people through dreams.
