We were all afraid of ghosts in childhood, and many still believe and are afraid of ghosts. If you like ghostly and mysterious themes, then check out the slots in the ghost theme on this website link.
Science is developing and there are already some logical explanations for why you could meet a ghost, or feel that you are being followed in an empty room. Interesting? Well, let’s get started.
The Impact of Infrasound
Human ears have a range of sensitivity: we cannot hear sounds with frequencies above ~20,000 Hz (ultrasound) and below ~20 Hz (infrasound). But these fluctuations still do not remain completely invisible to our bodies.
Experts from the National Physical Laboratory in England and the University of Hertfordshire have found that infrasound causes strange feelings in people: intense sadness, anxiety and frustration, chills, and a feeling that someone is in the room and watching them.
Unsurprisingly, infrasound in the range of 18.9 Hz — just below the threshold of human hearing — is referred to by some researchers as the “frequency of fear”. Such vibrations can affect not only hearing but also vision because human eyeballs resonate at about the same frequency. So spots in front of the eyes and other optical illusions add to the feeling of anxiety.
Most likely, you’ve heard of the Ouija board. This is a tool for spiritualistic sessions — a piece of wood with letters painted on it and the words “Yes” and “No”.
The principle of use is as follows: a group of people, put their hands on a tablet and drive it along the board. It is believed that if you summon some restless spirit and ask him a question, he will answer by shifting the pointer to the desired letters.
The participants of the seance, touching the tablet, unconsciously commit the so-called ideomotor act, when mental tension causes real muscle contraction. This is the “Carpenter effect”, which is named after the doctor and physiologist who discovered it in 1852.
Chemiluminescence of Phosphine
If walking through the woods or swamps you saw a glow and were afraid that it was a ghost, we will upset you. No, you just met the so-called will-o’-the-wisp. This phenomenon is often found in swamps. When organic matter — in particular, fallen leaves and water plants — disintegrates, it produces a chemical compound called phosphine.
Combined with oxygen and nitrogen in the air, it oxidizes and creates a ghostly, mystical glow.
So the swamp ghosts and lost souls that tourists and outdoor enthusiasts talk about are not aliens from the other world, but the result of phosphine chemiluminescence.
As you know, ghosts are especially often found in all sorts of gloomy abandoned mansions. The phrase “haunted house” has long been established in many languages. And such a love of the undead for uninhabited rooms is quite understandable from a scientific point of view.
Experts from the Independent Neurodiagnostic Clinic in Atlanta have found that spores of various types of fungi and mold that live in the humid environment of abandoned buildings, when inhaled, can lead to neurological and neuropsychiatric disorders.
Mycotoxins cause pain, disorders of motor functions, balance and coordination, irrational fear, delirium, and even dementia.
