The Effect of a Demon on a Person

I would never do an exorcism alone. So there's always other people that are present. Only myself, I will have somebody else with me and then the person that's possessed and then a family member or friend. Other people I've worked with have told me that once the demon took over, they lose all recollection of what was taking place. And when that happens, some are fully aware of what's taking place, but they feel as if they're a prisoner trapped in their own body. They're incapable of stopping what's takes place.
