I'm the Only One Who Can't See the Ghost Stories

[Weird stories + Dihua flow] Gu Zhao is an ordinary time traveler, and he still lives an ordinary life after time traveling. However, this world is a little strange, because the number of mental illnesses in this world seems to be too much. When he was an infant, his parents suddenly fell ill. They started to chop each other with knives while muttering "Holy Infant" and so on, and they cut Gu Zhao into an orphan. When I was a primary school student, a classmate suddenly fell ill and shouted, "Do it again, this time, I must--" Then he started foaming at the mouth and was taken to the hospital by ambulance, where he was diagnosed with split personality. When he was a junior high school student, the principal of the junior high school suddenly fell ill. He laughed wildly and "dedicated a pure lamb to the great god" at the opening ceremony, and then died of a heart attack on the spot. When I was a high school student, my high school classmates suddenly became nagging before the college entrance examination, asking everyone to talk about "curses" and "vindictive spirits". Eventually, the whole class except Gu Zhao was infected with pre-exam anxiety, and all of them were sent to a mental hospital. ——Finally, Gu Zhao survived while being squeezed between various mental patients, and stumbled all the way to college. However, on the first day of school, she saw a bunch of people holding a piece of white paper and crying bitterly, and howling about "strange rules". What did Jili Gulu say? Gu Zhao tore off the white paper with a "crash" sound, his face full of confusion. Apart from her, are there any normal people in this world? Mission: Believe in science
