If you watch any kind of paranormal movie or if you tell someone that you are dealing with a spirit, the first thing people do is grab a crucifix and start slinging holy water around. This rarely solves the issue. Growing up in the bible belt allowed me to witness this often and If anything I have noticed that it causes the spirit to get upset. There area few reasons why they get upset and "act out" more aggressively after that happens. Growing up in the bible belt allowed me to witness this often and pushed me to figure out why these methods don't work.
