Thinking about what I want to think about

What happens after you die. That was my big question. We all have theories but no one really knows what happens. Some people say that before you die you have a flashback about your whole life and you see everything you did. That is only a theory because no one really knows what happens and if that did happen to someone they are dead so they can't tell us if it really happened. This is what people think when they are about to die and not when they are dead.
