How can you understand what other people do when you don't even know anything that is happening in your mind? You don't understand how you ended up in jail for the murder of some random kid who happened to be at the same party as you. You ask questions and try to connect the dots, but it becomes clear to you that other people cant see the way you do. You begin to come to a scary realization about yourself while thinking and dreaming in your cell. Maybe you did commit the murder.
