Ghost Calls at the Door

There is an old custom in the village that three days before a person dies, a voice comes from outside the door at night, calling his or her name. If the listener does not respond, nothing will happen; if he responds, his soul will follow the sound and he will die within three days. This is called "ghost calling at the door". Before his death, my uncle said that someone called him outside the door. He responded. He is dead. Now it's my turn.
