A sociological survey has shown that 28% of people have at least once met with something otherworldly.
The Skeptical Investigation Committee, represented by its senior researcher Joe Nickell, spoke about the peculiarities of the human brain's response to ghosts. Joe has been researching this phenomenon for more than half a century, but during all this time he has not been able to find evidence of the existence of any otherworldly forces. He analyzed blood compositions, psychological aspects and many other parameters, but he failed to prove the existence of ghosts.
The main difficulty of the research lies in the complexity of the extraction of the raw material. Of course, he is regularly provided with various photographs, but they are not enough for full-fledged research. In movies, you can see how people detect the presence of mysterious forces using electromagnetic field meters, but in fact, there is no proven connection between ghosts and the magnetic field.
Science has its own view of encounters with the otherworldly. Sometimes a person is able to feel, see and hear what is not really there. Scientists call this a misunderstood view. Carbon monoxide, brain injury, or mental illness can lead to such visions and hallucinations. It is not uncommon for a person to see ghosts during sleep paralysis, which is experienced by about 8% of the population.
Sleep paralysis is the state between sleep and wakefulness, and most of the time it occurs in the morning. With such a phenomenon, a person cannot move his body and often observes visual hallucinations. Psychologists believe that sleep paralysis has its own special purpose: with its help, the mind tries to fight losses.
In addition, infrasound, which lies below our auditory range, can "call" a ghost. Such sounds can be made by car engines, whales and extreme weather conditions. Acting on a person, infrasound is able to lead him into depression, chills appear, a feeling that someone is watching a person, and much more. People usually attribute all this to the action of otherworldly forces.
