Learn some Latin, a few phrases that always sounds cool to go along with a possession character.

This is my third year as a scare actor in a haunt and this year I am portraying a sick possessed girl. I've done a bunch of research to try and at least find some behaviors I can mimick or some kind of tag line but I can't find anything. If you genius' could help me out I'd be forever happy. Please and thank you! :]
