The scene in Nocturnal between Josie and Victor in his office was not originally written as a dream. Jim Rapsas says the scene seems like a dream because of the way it was executed directorially. The special effects white-eyed Victor contributes greatly to the belief this scene is a dream sequence. Whether or not this scene is actually a dream, the only one who would know for sure would be Victor within the confines of the episode storyline.
