First of all, most schools are built in cemeteries or mass graves. Almost all schools in my hometown are like this. So it is inevitable that there will be some rumors. In some academic circles, suppressing evil spirits is also to gain popularity. In geomantic omen, this place is full of Yin Qi. As long as it is arranged by some masters, it is easy to get rich, students get high marks in exams and have played enough movies. What is Yin Qi heavier than mass graves? So these places are definitely more popular.
Second, schools are very precise and chaotic, especially universities. I believe that every university will have a death, sudden death at school or suicide fighting in love, and many schools are old. In the early days, when public security was not very good, it was inevitable that murders would occur. There is a J case in my hometown university. After several men pulled a woman into the stairwell of the classroom, the woman jumped directly from it. It happened that she was wearing a white dress, and then the rumor came out. Before she walked through the building at night, she heard a woman crying. Some people say that she saw a woman in white walking in the stairwell, and then the building closed. This rumor has been passed down to my generation. I don't know if it's true or not. I haven't seen it anyway, but the building is really closed. The teaching building was demolished last year (specifically, it was because of this rumor that the teaching building was closed, or the new teaching building of the school was under construction at that time, so I closed the old one, so it was just the time when the new teaching building was built)
Thirdly, it is rumored on the Internet that every university will have a basement, which is evil and has unclean things. I don't know if it's true or not. I hired an undergraduate tutor when I was in middle school. I sometimes go to their school on weekends. Their school really has a basement. It was really scary when I went in. This is like a sundry room, the innermost room is full of human anatomical specimens and props. It's dark. It's really scary. Later, when I grew up, I realized that many schools would store such specimens in the basement. In addition, the atmosphere is similar to that in ghost movies, so there are many students with wide brains out of thin air. Therefore, many freshmen hear that there are unclean things in the school as soon as they come, and wait until they become old students. It is handed down from generation to generation.
Fourth, after all, it is a school with many students. Coupled with the pressure of study, it is difficult to ensure that one or two students will not have a nervous breakdown. When a person has a nervous breakdown, he can do anything. The teacher may know why. But the students don't understand. There will be such rumors. I heard that someone in the class saw a ghost or was possessed by a ghost last night. Wait, wait, wait, plus the unique skills of China people. It's hard to infer.
Fifth, it is something that some people are boring.
