Actual, literal demons exist. They're not common, but they truly exist. Invisible touching, marks, voices, the name of Jesus Christ-it's all real and one night of it made me stronger-spirited and more courageous than wearing a uniform for a decade.

That said, like demons, actual possession to some obvious degree is extremely rare.
