What word are ghosts afraid of? Why?

The word that ghosts are afraid of is "exorcism". This is because an exorcism is a ritual or ceremony performed by a priest or other religious figure to drive out evil spirits from a person or place. Exorcisms are often associated with the supernatural and ghosts, and so ghosts may fear them because they are seen as a way of banishing them from a place or person. Exorcisms are also believed to be able to bind or bind the spirit to a certain place or person, which can be seen as a form of imprisonment for the ghost. This could be a major fear for ghosts, as it would mean they would be unable to move freely and would be stuck in one place.
