What are some long term paranormal events that have been scientifically explained?

Many people know the story of the pen fairy, light a candle, two people hold a pen with two fingers, draw a line in the middle, the two sides are yes or no, the pen will automatically draw a line to a certain answer, this is the answer that the pen fairy tells you. In the end, the expert explained that the principle was probably that the hand could not be kept still, and two people held a pen together, which seemed to have the power to pull, but in fact, the two of them shook together.

When I was a child, I often heard the sound of glass marbles falling to the floor upstairs. And especially at night. It's really oozing.

Because I was more timid when I was a child, my parents trained me and forced me to sleep alone, and every time I slept alone, I would hear someone upstairs playing with glass marbles. It was okay at first, because the family lived on the 2nd floor at the beginning. Upstairs is an aunt in a wheelchair who lives alone, I just came and wondered, that aunt's legs and feet are inconvenient and so leisurely to play marbles alone in the middle of the night?

Later, the family moved to the top floor, and it will be heard. It's scary to think about. I began to be afraid, and later after scientific explanation, I learned that it was the sound of tiny cracks in the concrete.

Affected by the closeness between the house and the surrounding environment, the height and density of the surrounding buildings, it can lead to the "refraction" and "accumulation" of sound.

Living tomb robbers blow out lamps. A candle is placed in the southeast of the tomb, and when the candle is extinguished, the vessel is immediately put down and the original way is returned, so as not to disturb the spirits of the dead. But if you lust for riches, you will be harmed by the spirits of the dead. The junior high school chemistry teacher told us to test the oxygen concentration with an open flame.

Because the people do not know the cause of ghost fire, they only know that this kind of flame mostly appears in places where there are dead people, and it flickers and appears, so this mysterious flame is called "ghost fire", which is considered to be a bad omen and a phenomenon of ghosts haunting. There are legends about ghost fires all over the world, but after they were defeated, it was explained that "ghost fires" are "phosphorus fires" and are usually found in the countryside and in graves on dry days in summer.

However, it occasionally appears in the city. Because human bones contain phosphorus, after the corpse decomposes, it will produce phosphine, which has a very low ignition point and can spontaneously combust.

I heard the sound of marbles upstairs before, and when I slept at night, I could always hear the sound of marbles upstairs, and then I asked my mother, who said that there was no one living upstairs, but at that time I was scared a lot, and only later did I know that it was the sound of concrete expansion and contraction.

Water tornado, many people call it a dragon to absorb water, all think that the dragon in the sky is drinking water, are very respectful of this phenomenon, and in the end it is found that it is a natural phenomenon, which is a strong vortex phenomenon in the atmosphere, mainly because of the evaporation caused by the heat of water vapor, and the formation of tornadoes is affected by various factors in evaporation.

America's Devil's Highway . The Grand Canyon has a U-shaped stretch of highway where cars frequently drive into cliffs about 500 stories (the depth of which is not officially given). Strangely, the accident occurred between 10:30 a.m. and 12 noon, and the car not only did not apply the brakes but increased the accelerator when driving down the cliff, so this section of the road is called "Devil's Highway" by the locals.

In the end, it was proved that because the midday sun caused people to lose sight of the guardrail, the drivers would not notice the cliff in front of them, which would eventually lead to the crash.

From Into the Science:

1. A child is often possessed by zombies. Do all sorts of weird moves. For example, rolling your eyes, biting, jumping forward with your arms and legs outstretched, and wanting to tear and drink blood, wanting to bite someone. The camera was dim, and many villagers were interviewed, and everyone was very scared.

Later, a professor was hired to investigate, but he still couldn't investigate. The professor dragged the child to the hospital of West China Medical University for examination, and the conclusion was that he was in good health. Finally, it is to take the little one to the psychiatrist.

The doctor asked a few questions, and in the end the result came out: it was because the child wanted to attract the attention of the family.

A peasant was still in the rural area of Hebei Province at 10 o'clock the night before, and woke up early the next morning to find himself in Nanjing. The family was also named "Shandong Gao Dengmin, Gao Yanjin" by those two people. The third time, he was carried on the back of the two and flew several cities.

The program was both pre-bureau investigation and evidence collection, and human and material evidence were found everywhere, and a few bird experts came, suspecting that the farmers were sleepwalking to Nanjing, Shanghai and other places. What MRI, CT or something, chasing people and farmers to check people, taking people's heads not for heads, but the results of the examination are not sick, people's heads are quite normal.

In the end, the results came out: it was the peasants who had paranoia, and this disease could not be detected.

3. A very strange thing happened to an ordinary villager in Caoban Village, Hua'an County, Fujian Province. In the middle of the night, with a loud bang, an unknown object fell from the sky, broke tree branches, smashed through the roof, sank deep into the ground, and smashed a pit more than ten centimeters deep in the ground. And the temperature is very high when it falls, and it feels very hot to the touch.

The villagers talked a lot, some said it was a meteorite, some said it was a part of an airplane, some people said it was UFO fragments, and even said that this thing seemed to be an alien urin, was it an alien object or another reason? What exactly is this unidentified object, and how did it end up here?

In the end, the result came out: it was a hawker who had a private tank of hydrogen and accidentally made the can, and the debris fell down.

4. Scientists used instruments to reproduce the experimental scene where people felt that there were ghosts behind them In an open and normal experimental environment, everyone could feel as if there was something behind them. These are just misjudgments made by the nervous system, a neurological disorder, like walking back from a capsule to find that you can't walk properly for a short time.

5. Some patients who were rescued said that they saw the tunnel of white light and felt weightless like their souls leaving their bodies, but scientists reproduced this scene in the gravity chamber, and anyone who could feel it through this experiment could feel that this was not a fantasy of the soul but a normal phenomenon in line with science.
