Liu Chen, who returned to the room, turned on the light, plunged into the bed, grabbed a quilt casually, and buried his head. Outside the window, it was raining, and the wind howled fiercely, as if it were about to tear apart everything that stood in its way. The continuous honking of the car accompanied by the sound of rain and wind, through the window, through the quilt, into the ears, along the ears, through the esophagus, into the stomach, mixed tastes, turning over the river and the sea. The heavens and the earth were spinning, and Liu Chen felt that now he seemed to have only a shell left, and his soul had long been unable to bear this earth-shaking feeling and fled.

"Knock, knock, knock", there was a knock on the door, and roommate Wang Fan shouted outside the door: "Order takeout, do you want to order it together, what do you want to eat?"

"No food, no appetite. Liu Chen replied.

"Are you okay, look at the appearance of the six gods when you come back, are you sick?"

"No, I'm fine, you can order your own food first, and then order takeout when I'm hungry." ”

"I'd better order an extra one, and eat it when you're hungry. ”

"Okay, thanks. ”

Wang Fan was Liu Chen's best friend in college, and after graduation, the two of them came to this fast-growing city and shared a house together in the central area until now. Wang Fan has a girlfriend, after graduating from the bachelor's degree, he went abroad for further study, and after completing his studies recently, he is ready to return to China for development, and he will marry Wang Fan one day, and then the two plan to return to the city where they studied to start a new career. In this strange city, it is not easy to have a sincere friend, so Liu Chen cherishes this friendship very much. Unlike Wang Fan, Liu Chen prefers to immerse himself in things he is interested in than falling in love, such as reading novels, watching movies and television, especially suspenseful, thriller, and weird works. Because he often reads at night, he fights until the second half of the night, and a pair of thick glasses are already leaning on the bridge of his nose when he reads.

After a while, Liu Chen remembered the 1999 suspense movie starring Bruce Willis and others - "The Sixth Sense" and the 2001 Nicole Kidman starring the same type of movie - "Island Horror". Death is not terrible, it is terrible not to know that you are dead, and what is even more terrible is not to know if you are dead. Thinking of this, Liu Chen felt a stream of frightened blood, rushing straight to the top of his head from his heart, intending to break through his skull, break free from the restraints, and burst out.

Looking at the time, it was already past 11 o'clock in the evening, and an idea popped into it. It is said that everyone has seven points of popularity and three points of ghostly spirit. When I looked in the mirror at twelve o'clock in the evening, I could see the hideous face of the three points of ghostly spirit. Liu Chen thought to himself, if he really didn't have that seven points of popularity, wouldn't he be able to see his true face now. If this "supposedly" is true, you can at least judge the truth of whether you are dead or not, and get peace of mind without having to be in a state of fear all the time.

The raging wind outside the window has quieted down a lot, the flowers and trees on the roadside are full of devastation, the road is paved with a layer of dead branches and leaves, and the rest of the crackling torrential rain is still unstoppable, still hitting everything exposed to the wind and rain. Liu Chen turned off the light in the room and scanned all corners of the room with the light outside the window. The time was almost up, Liu Chen stood in front of the mirror nervously, closed his eyes, and counted down "5, 4, 3, 2, 1" in his heart. The moment I opened my eyes, a lightning bolt outside the window lit up the sky, illuminated the room, and illuminated the whole mirror. In the mirror, there is only a tired, lonely, vicissitudes of face. Liu Chen couldn't help but laugh at himself secretly, believing this kind of nonsense he heard when he was a child. Lying back on the bed, Liu Chen decided to put aside today's experience for the time being and sleep peacefully. Perhaps, wake up tomorrow and everything will be back to normal, maybe it's just a dream.

In his sleep, Liu Chen vaguely felt that he was still taking the subway, and then a loud noise suddenly came from inside the train, and the dream came to an abrupt end. Liu Chen woke up, and it was already dawn.

Liu Chen felt it was time to make a phone call. He dialed his mother's phone, and "doodoo" rang several times in a row, but no one answered. Liu Chen's heart became impatient, and sweat broke out on the top of his head. Keep dialing, "Doodoo ......"

"Hey, Xiao Chen, why are you calling now?haven't you gone to work yet?" was Liu Chen's mother's voice.

"It's okay, ask you and Dad what you're up to, nothing else. When Liu Chen said this, his eyes were red.

"Your dad and I are fine, don't worry, you have to take good care of yourself when you're out alone. Mom said the same thing as usual.

After a few simple greetings and hung up the phone, Liu Chen closed his eyes and took a deep breath.

The next period of time was the same as in the past, washing, eating, and going to work, but Liu Chen chose to ride a bicycle when he went to work recently. Familiar streets, familiar flowers and plants, familiar high-rise buildings, walking through the streets, is like walking in a labyrinth of identical glass curtain wall buildings. For a period of time, it was so plain and uneventful. Liu Chen is sure that the experience of taking the subway that day was actually a dream he had at night because he was too tired, but the dream was too long and too real, which misled him.

One weekend, Liu Chen was ready to change the environment, go to the park not far away to breathe negative ions, and get rid of some nervous thoughts some time ago. The park is full of trees, birds, breezes, white clouds in the blue sky, and kites flying in the distance. Just when Liu Chen was intoxicated by this scene, a familiar face came to him, and the two passed by, stopping and turning around. Liu Chen was surprised to find that it was that girl.

"Hello, my name is Liu Chen, I seem to have seen you. Liu Chen said.

"I'm Wang Mei, we've met, on the subway. The girl replied.

Liu Chen suddenly froze, and a cool breeze penetrated his body, and he couldn't help but shiver. The previous idea that I was sure that it was a dream was shattered in an instant.

"This is not our previous world. The girl continued calmly.

"Isn't it the previous world?, what do you mean by that?" Liu Chen asked in astonishment.

"You can understand that you have left the previous world and come to another world, which is the world where you and I are staying now, which is a real world. The people and things around you have basically not changed, and the people and things you see do not appear out of thin air, they are all inextricably linked to you. Some people and things came into this world with you, like me. There are also many people and things that you have created yourself. ”

Wang Mei's remarks, if she were to be another person, she would definitely think she was a madman. But Liu Chen didn't think so, but he still interrupted Wang Mei, who was about to continue to make a tirade.

"Wait," Liu Chen said, "you just said that the people and things around you have basically not changed, that is to say, there are still changes, may I ask what this change is? Why do you say that this is not the world before?"

"Animals," Wang Mei said, "to be precise, the biggest change in the world now is the dog." ”

"Dog?" Liu Chen felt inexplicable, "What do you mean?"

"Think about it, have you ever seen a dog during this time, whether it's a big or small dog?" Wang Mei said.

Liu Chen thought back for a moment, "It seems that there is none, but maybe the requirements for dog ownership have been stricter recently, so there are not as many dog walks on the street as before." ”

"Do you have time?" said Wang Mei, "can you come with me to the nearby library? I can show you that what I said is not made up out of thin air." ”

"Okay. ”

"Don't you think I'm crazy?" Wang Mei asked, "I met Bao Ma who was in that carriage with us earlier, that is, the lady with the baby, and before I could finish speaking, she gave me a blank look and turned away, and muttered 'neurosis', you are strange, you actually listened to me finish this remark." ”

"I don't know why I'm listening to your headless nonsense. Liu Chen replied, "Let's go, while I don't have any other ideas now." ”

Wang Mei led the way, arrived at the library, and walked straight to the reference book area, she picked up a dictionary and handed it to Liu Chen.

"Look up the explanation for "dog". Wang Mei said to Liu Chen.

Liu Chen opened the dictionary and found the page about the word "dog", and was dumbfounded.
