EMF illusions
Though spirits are believed to cause random EMF spikes, it is important to remember the natural electromagnetic fields. A lot of times, uncovered wires and huge machinery give off high EMF readings. If a room is filled with bad wires, it will cause a high electric current to flow through the room, which is very unhealthy. Doctors have proven that high EMF situations can cause medical problems. If a person sits in an area for a length of time under these conditions, they may experience headaches, nausea, skin irritation, paranoia, and feelings of being watched, etc. As a scientific paranormal investigator, it is important to determine whether or not there are areas with potentially problematic natural electromagnetic fields.
