Sometimes also called electro sensitivity or electromagnetic hypersensitivity (EHS) - is a condition in which a person experiences physical or psychological symptoms reportedly aggravated by electromagnetic fields or other electromagnetic waves at exposure levels tolerated by the general public.
To date, controlled studies have not found the symptoms to be correlated with the presence of electrical fields or waves
Is sound with a frequency too low to be heard by the human ear. The study of such sound waves is sometimes referred to as infrasonic, covering sounds beneath the lowest limits of human hearing (20 hertz) down to 0.001 hertz. This frequency range is utilized by seismographs for monitoring earthquakes. Infrasound is characterized by an ability to cover long distances and get around obstacles with little dissipation.
Infrasound has been known to cause feelings of awe or fear in humans.
Since it is not consciously perceived, it can make people feel vaguely that supernatural events are taking place
Electrical sensitivity & Infrasound from Wikipedia.
Many believe that higher level electromagnetic fields can cause many unusual symptoms such as headaches, nausea, panic attacks, ringing in the ears, feeling vibrations, and dizziness to name a few. Other more severe symptoms include hallucinations, paralysis, psychosis and stroke.
Such is similar with Infrasound; it is believed to cause feelings of uneasiness in humans causing a variety of symptoms.
We know these things are there even though we can not hear, feel or see them. It is entirely plausible that infrasound and electromagnetic fields can have different effects on different people.
Certain animals are more in tune to infrasound than others. In fact many animals can hear and feel infrasound where as we humans can not. This could be a factor as to why we tend to think animals have a “sixth sense” about such things as earthquakes.
We can not say for certain that “paranormal” activity is caused by infrasound and/or electrical sensitivity, but they are some ideas to think about and to be aware of during investigations.
