Before Lan Tianyu left my office, he thanked me repeatedly. But I knew that it was just a polite act on the part of this student, and he didn't understand what was wrong with him.

This is normal, and even though I talked to him hungry for more than half an hour, I couldn't have cured his mental illness with just one conversation. Especially when I hinted that the state of affairs he was experiencing was nothing more than some obsessive nerves and fantasies at work in his brain, I clearly read the disappointment and resistance in Lan Tianyu's eyes. Obviously he didn't believe what I had to say, but he was very cultured and didn't directly express his distrust of me, but silently listened to my analysis and advice, and thanked me, saying that he would try to relax and reduce the pressure of studying - but I said it, and I could see that it was his courtesy, and he didn't actually listen to it at all.

After Lan Tianyu left, I sighed secretly - it seems that in order to completely cure his mental illness, there must be a relatively long-term treatment process.

There were no classes that afternoon, so I went to the gym for more than an hour, went to the bookstore, picked up a few new books, and then stayed in my bachelor apartment to read and surf the Internet. Yes, for a bachelor in my twenties like me, it's the most comfortable day to do whatever you want in your spare time.

The next morning, as soon as I arrived at school, I realized that something must have happened.

A police car is parked in front of the school. On campus, students gathered in the playground, looking frightened and talking. I passed by them, but I couldn't hear what they were talking about. I arrived at the office full of suspicion, and found that the principal happened to be talking to the teachers here, and the last thing I heard him say was, "Anyway, keep this matter quiet, so as not to have a bad impact on society." ”

I hurried over and asked, "Headmaster, what's going on?" ”

The principal glanced back at me, sighed, and said with some reluctance, "One of our school's resident students died unexpectedly in the dormitory early this morning. ”

"Ahh I was shocked, "Who is it?" ”

"Lan Tianyu from Class 12 of the first year of high school." The headmaster frowned and said, "Okay, don't inquire about this matter anymore, I just said it, this matter is ......"

"Wait!" I shook like an electric shock, "Who do you say is dead?" Lantian Yu! Lan Tianyu in Class 12 of the first year of high school? ”

The principal and several teachers in the office were stunned, and they clearly sensed that I was overreacting. The headmaster asked puzzled; "yes, what's wrong? Do you have any special relationship with this student? ”

I opened my mouth to tell them about Lan Tianyu's visit to me yesterday at noon, but I didn't say it—I didn't think I could tell this strange story in a few words. Besides, I have more important things to ask now.

"Headmaster, how did he die?" I asked hurriedly.

"It seems to have died of a myocardial infarction caused by excessive shock, and I don't know the specifics."

I was stunned for a moment, remembering the strange thing that Lan Tianyu told me yesterday, and a strange thought suddenly appeared in my mind. "Headmaster, you said that Lan Tianyu died in the early hours of this morning, so do you know the specific time of his death?"

"According to the medical examiner named Kang Wei, the time of death was between 4 and 4:30 in the morning." Speaking of this, the principal became more and more suspicious, "Teacher Yu, what is the relationship between this Lantian Yu and you, why are you asking in such detail?" ”

I completely ignored the principal's question, because as soon as I heard the name "Kang Wei", I couldn't help but immediately call out: "Ah, the forensic doctor is Kang Wei?" Thank you, Principal! ”

The principal and several teachers rushed out of the office as they watched me with puzzled faces.

Kang Wei is my high school classmate, and he has always kept in touch with me, and I thought that his career was not next to me, but I didn't expect that now there is a convenient time.

I quickly took out my mobile phone and dialed Kang Wei's number, and after a while, I heard his familiar deep voice: "Hey, is it Yu Yang?" ”

"It's me." I'll get straight to the point, "I'll ask you something, Kang Wei." Did you come to our school early this morning to have a body examined? A student named Lan Tianyu. ”

"Well, yes. What's wrong, what's your relationship with him? ”

"It's the teacher-student relationship." I didn't want to explain it to him in detail, but I was desperate to know the answers to some of his questions. "I want to ask, what exactly time did you find him dead?"

"Between 4 a.m. and 4:30 a.m." The answer was exactly the same as the principal had said.

"Can this time be more precise?"

He smiled. "Our current forensic technology can't be accurate to the minute or second. I can estimate the time of death within half an hour, which is pretty accurate. ”

I froze and didn't speak. Kang Wei seemed to sense my disappointment and said: "However, I did hear from one of the deceased's classmates about the situation - he was the first person to find out what happened, and he looked at the table below at that time and knew the specific time of the deceased's death - but, you know, our forensic doctors can't use this as a basis to infer it, at most as a reference." ”

"It's okay, tell me! When did he die? ”

The classmate said that the time on his electronic watch at the time was 4:16.

When Kang Wei said this, his voice was calm and his tone was flat, but he obviously didn't realize how much impact and shock this sentence brought me. When I heard him say "4:16", my head exploded with a "buzz". There is no doubt that this sentence confirmed the terrible conjecture in my mind. A strange and inexplicable feeling of horror permeated my whole body for a moment, leaving me stunned and unable to move.

"Hey, Yu Yang...... Yu Yang? What happened to you? ”

Kang Wei's voice pulled me back from my fearful imagination, and I calmed down and asked, "The autopsy you did showed that he died of a myocardial infarction caused by excessive shock, right?" ”

"Yes."

"Do you know what frightened him?"

"I don't know. But listening to the classmate who slept in bed, he suddenly heard an exclamation from under the bed in his sleep, and thought he was having a nightmare when he got out of bed, so he leaned over and called him, but there was no response. He got out of bed and took a look, and found that Lan Tianyu had staring eyes, his mouth wide open, his face was distorted and terrifying, and he was already out of breath - the one who went to bed was also half frightened, screaming to wake up the other two people in the dormitory, and then they notified the dormitory management department. ”

"You mean, Lan Tianyu may have been scared to death by a nightmare?" A fine bead of sweat permeated my forehead.

"I don't know, it's possible."

"Is there such a thing? I mean, people can be scared to death by a nightmare? ”

Kang Wei paused for a moment, and said, "I've heard of this kind of thing, but it's extremely rare—but, as I said, it's only possible, and I'm not sure if he was scared to death in a dream." ”

My brain was spinning, but it was a mess and I didn't have a clue. At this time, I heard Kang Wei say, "That's right, Yu Yang." I advise you to change schools if possible, I don't think the feng shui of your school's land is very good. ”

I was confused: "What? ”

Kang Wei said: "Did you know that our public security bureau will put together the files of cases that happened in the same place. When I put Lan Tianyu's file today, I found another file bag from a long time ago, and I realized that there was an accident in that place in your school eleven years ago. ”

"Ah...... I was still studying at the time. Why, could it be that there was a student death in the school eleven years ago? "I can't believe it.

"No, it's not the same thing. There is a student who has mysteriously disappeared. Kang Wei said, "And have you forgotten?" It wasn't the current high school, but a dilapidated elementary school. Because the school was so old, the school asked the construction team to renovate and rebuild some parts of the campus. At that time, there was a lot of confusion in the school where classes were going on and construction was going on, and as a result, there was a lack of management. A naughty first-grade boy disappeared like the world when he was in physical education class. The people in the school searched the campus all over the place, but they couldn't find anyone, and the guards insisted that they never saw any students sneaking out - you say, isn't that weird? ”

Hearing this, I understood a little: "That's because of this kind of thing, that elementary school was forced to close." Later, the current high school was built on this site! ”

"yes. But now something is even more serious in this school, and it is even more incredible - the boarding student actually died in his sleep for no apparent reason! That's why I said, maybe it's because the feng shui in this place is not good, and something will happen in exchange for it......"

Kang Wei continued to speak, but I barely listened to a word of what he said later.

In my head, I was thinking about a question over and over again-

Did Lan Tianyu really die in his sleep "inexplicably"? Or is there some unexpected reason?

I was reminded of the words he had said to me yesterday at noon, which made my hairs stand on end—

I was woken up by the same nightmare for three nights, both at 4:16.
