Reverse Exorcism

Here they will be trying to feel the person that they have induced a spirit in them. That's why it's reverse exorcism.

A clinic with dim lights with religious and scientific symbols here and there. People sat down on the bed, a doctor entered told that they will be facing reverse exorcism. A priest entered, holding Christ entered with his "ancient" book. They attached a brain-activity-checking machine to their head. The doctor, not the priest, started reading the things from the book like 'relax yourself, you may see a cut head or your mouth would start tweaking or fingers tinkling".
