This just blew my mind: “… Ferris Bueller, the person, is just a figment of Cameron’s imagination, like Tyler Durden, and Sloane is the girl Cameron secretly loves. One day while he’s lying sick in bed, Cameron lets ‘Ferris’ steal his father’s car and take the day off, and as Cameron wanders around the city, all of his interactions with Ferris and Sloane, and all the impossible hijinks, are all just played out in his head. This is part of the reason why the ‘three’ characters can see so much of Chicago in less than one day — Cameron is alone, just imagining it all.”
