My mom said that during the Vietnam war when her family was hiding in the jungle for months, some of the men would sneak back into the war torned village for utensils, salt, etc. Upon reaching the village, they would hear people and kids playing around and talking about. But when they go in the village, it's a dead ass ghost town. They would check all the huts and not a single person in sight. Since the Vietcong did shoot up and burned the village, it must be the ghosts that lived on.
