This novel seemed to contain multiple stories. It described a group of people taking turns to tell each other their experiences. Was some of the content not fictional?

I remember that the first story was about the protagonist living in a university apartment. Every night, he could hear someone knocking on the floor upstairs. According to the sound of the knocking, he drew a human figure. The brain was repeatedly knocked. Later, he found out that the former principal or teacher liked to eat brains. As he became more and more obsessed, he began to eat human brains. He was also tricked into eating steamed buns with brain dried powder…After that, there were several stories. At the end, a woman said that the stories they told were true but she hid the truth. In fact, the ones who told the stories were the real murderers in the stories. The woman was the one who deliberately trapped them.

Answer 1

I can recommend the book "Walking in Movies and TV Series." The protagonist traveled through different worlds, and each world was an independent story. There were also different characters and experiences, and each world was very interesting. It sounds like the plot of the novel you described. I hope you like this fairy's recommendation. Muah ~
