This is the reason I now simply Don't Feed the Demons here, as you know. They go straight to clergy per our rules. I have a lot of years of learning, but when it comes to that, I pass the baton and admit I simply don't know enough to take that on. I don't even know if clergy knows enough but they have far more "tools" to do the battle than I have.Which is the same basic message you and others here give to first time posters, usually youngsters, who play with Ouija boards and other like intended devices. And it's why I am comfortable with and usually avoid those discussions about demons and the like. I know there is way too much I don't know, and what I don't know CAN hurt me.
I know of at least 3 demonologists, GOOD ONES who know their stuff, who have had attachments or taken things home with them and had to get more outside help. Two of those have written books on the subject. This is why I am convinced we don't know what we think we know. It's waaay more, people. Perhaps beyond us to comprehend at this stage.
Keep the prayers strong and the shields up and don't poke the bears in the mystical woods out of curiosity.
