What does it mean to nail the sole behind the gate?

Superstition, my dad said that the daughter-in-law of a person in their village died and later married another one. But people who get married later are always in poor health and dream about their predecessors at night. Then find a shoe that I wore before my death and nail it, so that I will hang upside down on the door when my ex comes back at night. Nail shoes must have been worn by my predecessor. After ordering shoes and burning paper, your new body will be fine.
