Black Magick is not to be messed with. He could have opened a door or it could be attachment or generational now manifesting, one of many things but occult in nature. You need power to get rid of what has now shown itself to your son Dawn. Having these guys show up and tape record or whatever they do is like giving someone there shot at 15 minutes of fame. You need someone knowledgeable, pure, and a firm believer in Jesus to speak to you and your son to stop this. Your dealing with demons. Hopefully you read this. PS...Disregard the people and there comments. I know this stuff is real, they don't.
