Fight Club, the crazy yet ingenious theory exists that Marla is also another character dreamed up by the Narrator. Note that Marla and Tyler are very similar: both smoke constantly, wear the same clothes and rings, and even retain the same hairstyles. Marla, moreover, is in many ways similar to the Narrator and has the same problems: they both live in hotels; they change their clothes at the same time; they attend the same self-help courses — and there are plenty of other similarities besides. Marla may well be the female principle contained within the Narrator’s personality, existing at a time when he struggles with the masculine one within himself — Tyler Durden. Now rewatch the film with this interpretation in mind. Not even the cars notice her! -- source link
