This world seems ordinary to the naked eye but something affects the minds of the locals. The locals change their style of behavior randomly and in the pattern of a known genre of fiction. People remain basically the same, but the person they are is shaped by the prevailing genre. The most likely genres to be encountered are Screwball Comedy, Noir Detective, Classic Detective (Miss Marple, Nick & Nora, Nancy Drew etc.), Adventure, Cyberpunk, Sci-Fi, Fairy Tale, and Horror Story.

Physical details rarely shift, but behavior can shift on a dime.
