No! It is very real.... just as real as ghosts and demons

Demonophobia or Daemonophobia.
Demonic possession is a fantasy.
Faith-doubting holy man who encounters a case of demonic possession that could turn out to be real.

That is the correct spelling of "exorcism" (rite to drive out demonic possession).

Absolutely. There's still people who believe everything.
If one saw the movie, The Exorcist, they witnessed a reenactment of the Catholic ritual for demonic possession, also known as an exorcism, in which a priest drives the demon out of the host with the assistance of holy, blessed items such as a cross and holy water. Other religions such as Pagans and Jews have similar rituals.
I seriously doubt it since in 1990 Metallica was fairly heavy into demonic and satanist/occult style writing. More likely it was written with demonic possession in mind.
