Proper Ghost Removal
If it turns out there are natural explanations for your haunting, ask the investigators to explain them in detail—and don't be offended. You've asked them to give you an honest opinion, so you have to be prepared to accept it—whatever it is. If natural explanations cannot be found, and it's determined that there is indeed a presence in your house, the investigators will likely suggest you get in touch with a family minister so he or she can come to the house and to pray for the soul of the spirit that is present. This is not an "exorcism," but simply an attempt to get the ghost to leave in peace.
