Why is this happenin to my friend? THIS IS REAL!?

I googled SONNEILLON and its a demon of hate. I don't know if its a real demon or based on some kind of game. I dunno if your friend knows this. I wouldn't rule out some kind of personality disorder and your friend should see a doctor. But since I am a religious person I wouldn't rule out demonic oppression either. I'll be praying for your friend.
