The Role of a Living Person in Poltergeist Cases

In many poltergeist cases, what's actually happening is not a spirit, although some may have spirits involved. It's actually the living, a living person who's under stress and via their subconscious are venting their frustrations using psychokinesis. The resolution for the client then is to try to help them learn to manage their stress or redirect what's going on so that it doesn't manifest in this destructive way. That's basically what happens in the 21st century poltergeist case.
