Demon possession

Mental illness or demon possession?

I went to Gandalf’s (a prayer cafe) with my missional community to serve food to the local East Austin community. Overall, it was a really great experience, and Gandalf’s is doing a great thing for the community. There was a lady that was roaming the area who had a very apparent mental illness. She was talking constantly to no one and everyone and yelling occasionally at us and others. She came to get some food from us, rambling and yelling along the way and throughout the night. She was also pretty rude about how much food she got. One of the girls with us suggested that this lady was demon possessed, that Satan was possessing her to scare us and others away from something good.

Do you think demon possession exists? I’m not so sure…

P.S. I just google image searched “demon possessed” and really scared myself.
