I believe that as long as I am a Chinese, I have heard about supernatural events related to "ghosts hitting the wall" since childhood, especially those friends who have lived in the countryside since childhood.
A few decades ago, it was not as developed as it is now, and many people walked on their legs when they went out. If you go out well, you can go home before dark.
However, there are always times when things don't go well, and if you want to rush home, you have to walk at night. It's easy to encounter supernatural events such as ghosts hitting the wall, which is also strange, and ghosts hitting the wall are always associated with the night.
Therefore, the older generation, because they often walk at night, some encounter ghosts hitting the wall, and some have not encountered it, but the people around them have experienced such a thing.
Objectively speaking, the supernatural event of ghosts hitting the wall does exist, and it is precisely because of this that the spread of ghosts hitting the wall among the people is very high.
In fact, ghost hitting the wall is not a unique supernatural phenomenon in China, this phenomenon also exists abroad, but it is called differently abroad, but the meaning is almost the same, that is, getting lost and returning to the original point.
From this point of view, the phenomenon of ghosts hitting walls is a common phenomenon in the world, and because of this, many scientists expect to find out the scientific basis for ghosts hitting walls through scientific means.
Early research thought it was a problem with walking habits and legs
At the beginning of the 20th century, some scientists tried to explain the phenomenon of ghosts hitting walls through scientific means, because most of the phenomena of ghosts hitting walls appeared at night, scientists judged that this phenomenon must be related to light. In other words, when the light is bad, the human eye cannot distinguish the direction.
This is indeed a necessary condition for ghosts to hit the wall, but some people will also have the phenomenon of ghosts hitting the wall in their familiar environment, so it is not the light problem that can be explained.
Then there must be an internal reason, which induces the occurrence of the phenomenon of ghosts hitting the wall, and in order to find out the reason, we can only find some experimental subjects and conduct comparison experiments.
Due to the limited technical means at that time, the experimental process was relatively simple, that is, a dozen people were found, and then a forest was found, and in order to restore the scene as much as possible, the experimental process was also carried out at night. The subjects were blindfolded. These subjects are then asked to step out of what they think is a straight line.
But in the process, no one walked in a straight line, either to the left or to the right, and there were some people who went around in a circle.
Judging from the results of the experiment, those who go around in circles within a certain range are the so-called ghosts hitting the wall. In the experiment, those who did not go around in circles also deviated from the direction of travel.
Based on the results of this experiment, the scientists came to two conclusions:
1. Everyone has their own walking habits, some like to the left, some like to the right, and the phenomenon of ghosts hitting the wall is related to walking habits.
2. The length of each person's legs is different, although the left and right sides of the person are generally symmetrical, not absolutely symmetrical, there are always some differences, such as the length of the legs is different.
The second experiment solves the mystery
In the early 20th century, due to the limited technical means at that time, it proved that the phenomenon of ghosts hitting the wall did exist objectively, had nothing to do with "ghosts", and was not a supernatural event, but this simple experiment was not very convincing.
After entering the 21st century, some scientists have used advanced means to unlock the secret of ghosts hitting the wall.
In September 2009, a scientist from the Max Planck Institute for Biocontrol in Germany, Jan J. Jan L. Souman, led a research paper related to this topic in the journal Current Biology.
The content of this paper is also that they conducted experiments on ghost walling, and analyzed what is the main reason for the occurrence of ghost walling.
Soman retrieved a total of 15 test subjects, blindfolded all of them, and each wore a GPS, which was used to record their walking routes. The task of these subjects was very simple, which was to walk in as straight a line as possible through a wide open space.
Judging from the results of the experiment, there is not much difference from the experiment at the beginning of the 20th century, most of the people are moving left or right, and a small number of people appear in place with a radius of only 20 meters.
In other words, there was a "ghost hitting the wall" in a small area, and afterwards, according to the experience of the test subjects, they all thought that they were walking in a straight line, including those who were circling in circles.
This experiment also overturned the conclusion of the previous experiment, and they treated each subject's shoes so that there was absolutely no difference in the height of the subject's legs while walking.
But even so, there is still a phenomenon of ghosts hitting the wall, which means that the phenomenon of ghosts hitting the wall has nothing to do with external factors, but is caused by some internal factors.
In addition, there is an interesting phenomenon in this experiment, which is that no matter what the radius of the circle is, and what the way it goes around, they will eventually return to the starting point.
In addition to experiments on humans, scientists have also done similar experiments on some animals, they blindfolded the mallard, and then took it to an open field, threw it into the sky, and finally found that the flight trajectory of the mallard in the sky is also a large circle.
From the experiments on animals, the results are the same, that is to say, animals will also have the phenomenon of ghosts hitting the wall, and animals don't even know what "ghosts" are.
Eventually, Jen L. Soman concluded that it was not the legs that caused the left and right circles, but the small differences between the left and right vestibular systems in the brain.
The vestibular system is responsible for the balance and spatial perception of the body, in a space with a poor line of sight, people are easy to lose their references, especially when walking at night, people are prone to nervousness and fear.
Especially in some unfamiliar environments or in the cemetery, this fear will be aggravated, and people's judgment will be reduced, and the ability to observe the surrounding environment will also be reduced.
At this time, due to the slight differences in the vestibular system, they will send a wrong signal to think that they are walking in a straight line, but in fact they are indeed deviating from the straight line, but are circling in circles, and there is a so-called "ghost hitting the wall" supernatural phenomenon.
In fact, it is very simple to break the ghost wall, first of all, to ensure that your emotions are stable, do not panic, use navigation when there is navigation, turn on the light to find a reference when there is no navigation, if there is no electric light, then look for the North Star to judge the direction.
And if you don't have any of these, you can use some surrounding environments such as trees to determine the direction and get out of the dilemma of going around in circles. Of course, it is best to try not to walk alone at night in a deserted place.
