You are dead. You are left there, your soul is wandering through Earth, with nothing to do, with no thoughts, no feelings, nothing at all, anymore. You have nowhere to go, and no one you can talk to. You can't go back now. Everything has been done already, all the people you knew, all the feelings you had, all the things you did. The things you did are still there, in the heart of everyone, but your soul is forgotten for the rest of eternity.
