Demon who claims to be mother earth?

I know this might make a lot of people mad, but i work in a homeless ministry and we have a new person who is defiantly demon possessed but the being claims to be mother earth. Can anyone give me information on it? I've tried Google, Bing, Yahoo, and Ask.com but nothing has come up. I don't want criticism or snappy ignorant people either. So if you can help with out leaving your opinions it would be greatly appreciated.
