My mom had told me this story alot of times and I always get scared. Here it goes if you want to read it.
One time my mother’s sister and her friends summoned the Devil and when they did, the person who was named Mark was laughing. All of a sudden his eyes turned green instead of brown. He flew back and forth. When they brought out the bible, his eyes turned back to brown as before.
I don’t think this is scary but if you believe in the Devil, well that’s a different story.
