March 15th Tim Harte Apparitions, Hauntings and Poltergeists and MESA A Multi Energy Sensor

A presentation from Parapsychology Research and Education (also known as ParraMOOC2023), Recorded on March 15th, 2023

Abstract: MESA is a computer system specifically designed to measure energies associated with haunt and poltergeist phenomena. We have measured over 250 sites since 1994. We measure infrared, visible, ultraviolet light, vibration, electromagnetic fields, geomagnetic fields, random number generators, barometric pressure, humidity, and temperature. We will present and discuss preliminary findings after a review of the timeline of apparitions, hauntings, and poltergeists.”
