Five Hours After Death

The world is like this. When you live your life day after day, there will always be an accident for you. For example, right now, I am returning home from school for self-study, and I go straight on the green light. A truck turning left turns overloaded and rolls over. So I died inexplicably. Of course, it may have been too sudden, or maybe my brain has not died yet. My consciousness still exists in this world, and I don't know when it will dissipate.
