“There was a baseball game on but it didn't look real. It was guys in uniforms playing games on a deep green field. They were playing baseball as if baseball was important and as if all the world wasn't in jail, watching them from a completely different world.”
This shows that we all tend to believe that what is going on in our world is the only world in which something is going on. We believe that when we stop, time stops, and that the only reality is our own.
