The Difference Between Perception and Outward Reality

There's a difference between saying that we all perceive the world differently, and therefore, it feels like we live in different worlds. In Washpop Fiction, there's this famous sequence where they open up Marcelis Wallace's case and peer inside. And Pateratino was asked, what's inside the case? He refused to say because he said everyone is taking their own imaginative framework and putting something in the box. There could be any number of empirically equivalent worlds.
