There have always been many legends about "haunting" at home and abroad. There are also various speculations about "ghosts". Some people think that they are caused by mental stress that leads to hallucinations. Some people think that it is the influence of the natural environment, such as scratching. The weird atmosphere created by wind, rain, lightning, etc.... British scientists also began to conduct various scientific experiments, hoping to use scientific weapons to uncover the mystery of the "haunting".

Richard, a famous British psychologist. Wiseman conducted such an experiment at a concert, adding low-frequency sound waves, that is, infrasound waves with a vibration frequency lower than 20 Hz, to four pieces of music played.

After the music was played, Richard. Wiseman asked listeners to describe how the music made them feel. Audiences present said that they had a series of strange feelings when the music was played, such as uneasiness, sadness, disgust, fear, etc. Some people even felt a chill on their spines, which is similar to what people feel when they are "haunted" Very similar.

Professor Wiseman believes this shows that infrasound waves can greatly enhance the sensations you are already experiencing. For example, you may feel a little nervous at first, but after hearing infrasound waves, you will feel even more nervous.

This experiment proves that there is indeed a connection between infrasound waves and various strange sensations. Moreover, the frequency of infrasound waves is lower than 20 Hz, which is beyond the hearing limit of the human ear, so people will attribute it to ghosts and ghosts, etc., resulting in a more frightening feeling.

There has been no relevant research done in China on whether various "haunted" phenomena are due to infrasound waves, but judging from the scientific research conducted by British scientists, it is still possible.

Why can ghosts see people but people can’t see ghosts? In many horror legends, ghosts and people are in different spaces. Ghosts can see and tease people, but people can’t. No ghost. Such things are often heard in reality. According to legend, some people have yin and yang eyes and can see ghosts, so why can’t ordinary people see them? What about yin and yang eyes?

What we know Ghosts are believed to be the souls of people after death. If you have great anger and resentment during your life, you will become a ghost looking for your enemies in life. Therefore, there is a folk saying that if you don’t do anything wrong, you won’t be afraid of ghosts knocking on your door.

The ghosts discussed in Buddhism are different. Ghosts are considered to be just one of the five living beings, which means that after death, a person may ascend to heaven, continue to be a human, or fall into the state of an animal. It is possible to go to hell, and of course it is possible to become a ghost. However, the possibility of becoming a ghost after death is only one in five. It does not mean that a person will definitely become a ghost after death.

Another characteristic of ghosts is their fear. Normally, we always think that ghosts are very scary, so when we think of the ghost’s green-faced, fanged image, and its claws and fangs, our hair stands on end. People don’t know that ghosts are more afraid of people. We usually hear two idioms describing ghosts, one is sneaky and the other is harboring evil intentions, which shows that ghosts are also very afraid of us.

Usually people cannot see ghosts, but ghosts can see people. When they see us, they will be frightened and hide quickly. They dare not come out until we pass by, so we don't have to be afraid of ghosts at all.
