Early Warning Sign of Paranormal Activity
A barometer is a scientific instrument used to measure atmospheric pressure. It can measure the pressure exerted by the atmosphere by using water, air, or mercury. Pressure tendency can forecast short term changes in the weather. Numerous measurements of air pressure are used within surface weather analysis to help find surface troughs, high pressure systems, and frontal boundaries.
Some ghost hunters believe that paranormal activity created from a ghost or spirit can change the atmospheric pressure and thus a barometer may help detect paranormal activity.
This atmospheric pressure may aid the ghost hunter in warning them of possible activity about to unfold. It can be used as an early warning sign/signal that something is about to happen above the normal.
Low pressure has been associated with thunderstorm and cyclone activity, and some investigators believe that ghosts might take the opportunity to manifest during thunderstorms because of the availability of energy.
This form of energy would be able to be detected using a barometer. Although a barometer can measure normal activity such as weather it is believed that a barometer can help aid the ghost hunter as a early warning signal that paranormal activity may arise.
Many ghost hunters report that when paranormal activity is about to commence there is a change in pressure around them and the temperature and humidity generally drops rapidly as well as ion activity appears to increase. Much like when a thunderstorm is coming within your area you sometimes feel a static like energy in the air.
Some people and animals tend to get excited and feel energy during a thunderstorm and this type of energy is believed to possibly be used by entities to manifest themselves. This energy and change in the environment would be able to be detected using a barometer.
