When the bell rang for the end of class, the quiet classroom seemed to suddenly become noisy like a pot of boiling water.

After watching the teacher leave the classroom, Pei Chu carefully took out a domestic smartphone from his pocket and typed a sentence in the browser search box-

Why do people have the same dream over and over again?

Soon a large number of answers to this question popped up on the browser, and Pei Chu randomly picked a few answers and looked at them, all of which were similar to the same clichés about the subconscious, memory, and real-life pressure.

The scientific way of saying is that people dream every night, and many dreams may be the same, but they can't remember it when they wake up, and after being stimulated, they may repeat the cycle.

There are also a few answers about the mystical side, saying that dreams are unnatural forces, but ordinary people don't use them, but some people can apply these powers in certain situations.

Pei Chu quickly flipped through a few answers, some of which he could understand, some of which he felt were not particularly easy to understand, and some philosophical, psychological and metaphysical words were thrown out, and he saw it a little foggy.

Then, he went on to type a question into the browser - why do you dream within a dream?

The answer is actually similar to the question above, it is some realistic reaction or something, or it is either a mysterious topic such as consciousness.

Some of the explanations were very absurd, and Pei Chu felt that they were not interesting after watching it for a while.

"It is said that dreams reflect reality, but the two dreams I had seemed to have nothing to do with the environment and experience I lived in."

Pei Chu seriously recalled his recent life, including the novels, movies, television, and games he watched, and it seemed that there were no strange scenes in his dreams.

In the first dream, he remembered it most clearly, it seemed to be another life experienced by himself, extremely real. In Pei Chu's own words, it is a bit like playing a real simulation game, or a movie that substitutes himself for the script.

The second layer of dreams seemed to be covered by a layer of black cloth, and although he remembered it, it felt like it was always one layer apart, and it was not so real. Only, he was sure he remembered.

But some of what he saw in it didn't quite look like he had made up his brain.

"What the hell is this?"

Pei Chu picked up the pen on the table, flipped through a blank homework book, and slowly traced a pattern that looked a bit like a flower following his memory.

The dilapidated room in the dream on the second floor, the style and layout, he had never seen him. And the pattern he just drew was the carved details on the screen and door frame that he remembered.

He had dreamed before, but no matter how real the dream was, it was difficult to restore such a clear composition, not to mention the almost real life experience in the first dream, which made it impossible for him to distinguish between the dream and the reality.

Moreover, more importantly, this dream within a dream he had was not the first time, and it appeared again and again, making his whole person a little confused.

"Let's go back and think again!"

Seeing that he couldn't find an answer for a while, Pei Chu was ready to stand up and take a walk in the corridor to take a fresh breath, so as not to fall asleep again when class was held.

Just as he was about to stand up, he heard a sudden excited shout from the front table.

Pei Chu raised his head and noticed a young man with gold-rimmed glasses at his front table, holding a mobile phone and suddenly shouting: "It's released, it's really released!" ”

"What's released?"

Before Pei Chu could speak, Peng Cheng, who was lying on the table and reading the novel, was also attracted by the movement in front of him, and suddenly stood up and leaned out half of his body in front and asked.

"Power Armor Released!" The young man with gold-rimmed glasses who turned around looked a little excited, holding up his mobile phone and shouting, "I can't imagine that there is really an application product, it seems that it has not been a few days since the walking robot last time." ”

"Jiang Pengyu, show me the video."

Peng Cheng's voice became eager, there are few boys of this age who are not interested in game novels, as well as robots, artificial intelligence, and the like.

Although the grades of several people are not very good, they pay much more attention to this information than other "good students".

The young man wearing gold-rimmed glasses turned his head, didn't pay attention to Peng Cheng, who was about to press over most of his body, but handed the phone to Pei Chu, "Pei Chu, take a look, is this like the power armor in that movie?" ”

Pei Chu glanced at it casually, and what appeared on the mobile phone screen was a man about thirty years old, with a somewhat simple metal shell holding many wires on his hands, feet, chest, waist, etc., which looked not light, and it should look very clumsy, but the man who was wearing it was very flexible in his gestures, from the movement of his fingers to walking and small jumps, it was not much different from a normal person.

"Huh...... Really! ”

Pei Chu, who originally had some tinnitus, was a little energetic, and he remembered that some posts on the Internet before said that they were conceptual products, and in the research and development stage, there was a finished product now.

"Oh my God, this ...... This ......" Peng Cheng, who had been probing his brain, also saw the picture in his mobile phone, and couldn't help but exclaim excitedly, "Will it be a mecha warrior in the future?" ”

As he spoke, he danced and made a few animations of piloting the mecha, which seemed to be extremely invigorating.

"It's just an outer metal skeleton." Looking at Peng Cheng's excited appearance, Pei Chu explained aloud, and then stretched out his finger and pointed to a few places on the screen of the mobile phone, "The battery has not been solved yet, and if it can't solve the energy problem, it will be difficult to apply it on a large scale." ”

"That's right." Everyone has discussed this aspect many times, and Peng Cheng obviously understands, his tone is slightly lower, and he sighs: "It would be perfect if there was the ark reactor in the movie." ”

"If we could have that kind of energy, we would be the fourth industrial revolution." The young man with gold-rimmed glasses stretched out his slender middle finger and pushed the frame on the bridge of his nose, and replied disdainfully.

"How is it impossible, maybe in two years...... Alas, you come to this gesture again, you don't know when I do? Peng Cheng was scolded by Jiang Pengyu, a little unconvinced, especially watching him push his glasses, he suddenly shouted with some shame.

"What? I just pushed my glasses. Jiang Pengyu had an innocent expression, and pushed the eyes on the bridge of his nose with his middle finger at Peng Cheng.

"You're still here?" Peng Cheng wanted to rush over and pinch the other party's neck.

For some high school students, some information related to the frontiers of science and technology is actually more topical than games, sports and the opposite sex.

Pei Chu remembered that when the video of the mechanical dog that couldn't be kicked down was popular on the Internet, the few of them were also chatting enthusiastically.

Of course, in the end, Peng Cheng and Jiang Pengyu also started to fight as always.

Although Xiushui High School is just a middle school in a small county, most people have mobile phones under the invasion of the Internet tide nowadays.

All kinds of network information, fresh scientific and technological news, etc., will not know much less than people in big cities. The fanaticism of many little girls in Weibo to fan celebrities has made many boys a little dumbfounded.

Pei Chu's eyebrows were a little swollen by the quarrel between the two, and he returned the mobile phone to Jiang Pengyu and stopped the two from fighting, "Okay, okay, don't make trouble, the noise makes my head hurt." ”

"You're not sick, are you? Do you want to go to the hospital? Jiang Pengyu at the front table looked at Pei Chu's table mate and stopped playing with Peng Cheng.

"Pei Chu said he always had nightmares."

Before Pei Chu could answer, Peng Cheng next to him had already spoken first.

"Nightmares?" Jiang Pengyu showed an inquiring look.

"It's not a nightmare, it's just that I don't sleep well."

Feeling the faint swelling pain in the center of his eyebrows, as well as the tinnitus in his ears, Pei Chu didn't want to continue talking.

"Okay, you go back and take more rest."

……

After a day of classes in a groggy state, after school in the evening, Pei Chu refused the invitation to have dinner with Peng Cheng and Jiang Pengyu, and left the school straight home.

He is now a sophomore in high school, and he has self-study in the evening, but Pei Chu feels that he has no energy at all and does not want to continue to stay in school at all.

After coming out of school, he took a bus and went straight to a large urban village in Nancheng District.

The streets and alleys of the urban village are a little narrow, probably because it is just the rush hour in the evening, the shops along the street are open, the sound of stir-frying and selling is endless, the lights are bright, the flow of people is like weaving, pedestrians, tricycles, motorcycles shuttle among them, the occasional delivery van and car are blocked, and the horn is slamming loudly.

After eating fried rice noodles at a rice noodle shop on the side of the street, Pei Chu returned to his residence along the narrow path.

He now lives in a rented house in an urban village, about 40 square meters, with one bedroom and one living room. The furnishings of the house are not complicated, except for a bathroom, only a single bed, cupboards, and a desk full of books and miscellaneous exam papers.

Pei Chu's home is in a mountain village dozens of kilometers away from Xiushui County, when he was young, the conditions were not very good, and later his parents followed their relatives to Linhai City to open a snack bar.

The year before last, the family still had a three-story self-built house on the homestead of their hometown, and their parents also bought a scooter worth more than 100,000 yuan, and now they are saving money to buy a suite in the city.

Pei Chu's high school, Xiushui Middle School, is not a closed high school with very strict management, and the county middle school naturally has its own characteristics, there are boarding schools, and there are also many day students.

Although Pei Chu moved out of the school and rented a house outside, he used the excuse that the dormitory was too noisy and not conducive to studying, and in the end his parents reluctantly agreed and let him rent a room outside.

After returning to the rental house, Pei Chu threw his schoolbag to the table next to him, and suddenly felt that the whole person was so sleepy that he couldn't open his eyes, his spirit had been very weak in the past few days, and he didn't take off his clothes, he just lay down on the bed and fell asleep.
