Keith Linder, 3.7.21 - Poltergeists and Physics - Starting with Fire
Suspect Poltergeist activity? Call a believer with knowledge and prior experience defusing similar situations ASAP. Arguing about the existence of such things is moot at that point and provides the Poltergeist an opportunity to get a stronger foothold.
Big transformation since the initial introduction to an invisible foe  - when Keith was completely waylaid by a force few seemed to have any reliable method to account for. (And some preferred not to account for.)
Since then, first hand experience and working with knowledgeable others who were schooled in tracking Poltergeist behavior has provided an education, so much so, that he is now able to offer support and insight to others in a similar predicament.
Keith's books are on Amazon - Link.
Quick revisit of book 1: Do not - repeat - do NOT antagonize a Poltergeist. Keith remembers the specific action that turned up the heat on the poltergeist activity - resulting in a shift in focus - it began targeting him.
Book 3 - Poltergeist - The Night Side of Physics takes other poltergeist cases into account and compares common themes and potential causes or key similarities in targets. What clues can science provide? New questions. New answers. [Stop blaming the victim.]
