You may be on to something here.
Several times yesterday I wanted to suggest the possibility that he may be demon possessed, but held back because I felt it would be as bad as all the others tossing out accusations without any proof to back it up.
This sure looks like there is a possibility he was dabbling in the occult and opened himself up to demon possession. I'll still reserve my opinion till there is a lot more evidence from good sources though.
I may be criticized, but I agree with you, Apple Pan Dowdy. The fact that this young man can walk into a classroom and everyone in there with him senses something fearful in the room, that something is not right, and his tie to the occult, really gives credence to the possibility that he could be possessed, or close to being possessed, by the demonic.
