I can confirm that there are christians who believe in magic, witchcraft, ghosts, spirits and demonology.

My dad slipped a disk in his spine one day when I was a child and passed out due to the pain. He woke up in hospital after emergency surgery and to this day has a huge scar. I remember my Grandad, who was a surgeon at the hospital and always told me shit straight up regardless of my age, informed me of the "gory" details regarding the surgery. A few days after the surgery I remember a pastor from our church came to visit my dad with us. He gathered us around and informed us how a demon had climbed onto my fathers spine and ripped the disk out, and that it was the church's prayers that had cast away the demon - completely disregarding the work of the surgeons.

I think that was the first time I had atheist thoughts and saw the true nature of the church - malicious and brain-washing. Even as a child I knew that demons didn't exist and they were the stuff of myth and fiction. I was then told by the pastor that I am possessed by a demon who was putting these thoughts into my head that demons don't exist, when I questioned his idiotic logic.

To this day my parents still believe in demons and ghosts. I have an undiagnosed sleep condition and my sister has narcolepsy, and my parents straight up say it's because we are "cursed" or "possessed".
