Just as that’s not how exorcism works, demonic possession is not like what it is in the movies. Usually, in the Catholic Church (which I’m a member of, by the way), the victim does not give consent to be possessed but inadvertently triggers it by doing something related to the occult that they really shouldn’t have. Usually, symptoms include sudden manifestation of superhuman strength without proper dieting and exercising and often unnatural for the victim’s age (this usually manifests with losing control of one’s personality and can cause others to be attacked), a sudden change in the victim’s voice, speaking in foreign languages without having previously learned them, the ability to have distant and hidden knowledge without previously knowing it (including a sudden ability to predict the future, usually in dreams), an ability to levitate/move/expel objects, and especially a tendency to become averted to sacred objects at best or at worst blasphemous and enraged at the same time (often entering into a frenzy if not outright rage) along with constantly making obscene gestures and overuse of profanity around such objects. This may include antipathy at entering a church building, speaking Jesus’s name, or reading/hearing scripture.
