The faint crying sound suddenly became hysterical, and then gradually evolved into a broken roar with no content to be heard, accompanied by the cold wind of resentment that seeped into the house from the crack of the door.

It was as if someone was scribbling on the wall with a crayon. The already distorted graffiti became even more difficult to recognize. The chaotic colors quickly covered the entire wall, covering the neat and unclear award certificates.

"Cuckoo, cuckoo, cuckoo, cuckoo."

The time signal at four o'clock ended, the cat head opened its blood-red mouth, and the rusty mechanical cuckoo bird rolled to the ground and broke into pieces.

A ball of flesh and blood grew from the broken abdomen of the mechanical bird, quickly wrapping up the mostly rusted cold iron sheet.

In the public toilet, a black shadow quickly escaped into the depths of the shadows.

Robin stood in front of the sink, wiped the red paint off the mirror for the second time, and lowered his head to confirm the time: "Considering the conversion with the real time, this should be four o'clock... a special time point."

He subconsciously wanted to record all this with the recording pen, but thinking that this was in a dream, he opened the cap of another pen and hurriedly wrote a line of words on his cuff.

When the cat-head wall clock sounded again, Robin was trying to change the style of his new watch. When he looked up, he found that he was back in the public toilet.

"I didn't move, nor did I pick up food randomly. It shouldn't be a teleportation triggered by some of my actions."

Robin put away the recording pen, returned to the mirror, and carefully observed the young version of himself in the mirror wearing a dirty school uniform and bruised face: "This injury is different from the previous one. Is there any special meaning?"

Robin pondered and reached out to touch the mirror.

The touch from the fingertips was hard and slightly cool. There was no special chill, and there was no situation where the "him" in the mirror was suddenly pulled in.

Compared with ordinary mirrors, there is actually no obvious difference.

The only special thing is that the wounds and bruises in the mirror can also feel obvious pain, as if they are real.

"Is there a possibility that this mirror can actually awaken people's dormant memories? I was often bullied when I was a child and was locked in a toilet cubicle, but my inner self-protection mechanism made me forget these painful experiences and mistakenly thought that my student days were very happy..."

Robin took the electric saw and carefully checked his memory, ruling out this possibility: "It shouldn't be. I have always been an ordinary student who is very inconspicuous. I don't have similar psychological shadows. After graduation, I was assigned to be a kindergarten assistant."

According to Robin's understanding of social news, with the continuous development of the field of psychology, by 2052, many professions have introduced complex personality model measurement mechanisms.

For far-reaching professions such as teachers and doctors, only when the psychological measurement results meet the standards can they be successfully employed.

Robin washed the rag and hung it back, turned off the faucet, walked to the door of the public toilet, and looked into the corridor.

The narrative has been taken without permission. Report any sightings.

After ruling out this possibility, the possibility that this memory belongs to the dream itself has greatly increased.

Combined with Ling Su's analysis, the strong depression and anxiety reflected in the dream have also found part of the source.

But the information currently known is still extremely limited, not enough for Robin to figure out why he returned to the public toilet, nor can it explain the cause of these terrifying monsters.

"I am a middle school student who is often bullied. I have different injuries on my face every day, and my school uniform is often deliberately dirty... At this time, I will urgently need to find a relatively safe place."

Robin looked at the mirror, and the boy in it hid behind his face, his thin body huddled in the dirty school uniform.

Robin tried to put himself in the dream's shoes: "Four o'clock is a special node, why?"

"The wall clock cannot distinguish between morning and afternoon, but if it is four o'clock in the morning, only boarding students will be in school, and the layout of that bedroom does not look like a student dormitory."

"If it is four o'clock in the afternoon... middle school students should not eat dinner so early, it may be the afternoon break, or free time."

"For the owner of the dream, this is the time when a nightmare begins."

"At this time, something terrible will happen. I have to find a place to hide, a place where no one else can find me."

"I am very scared. There are shadows of those people everywhere. I can't be caught. If I am caught, I will be beaten. I can only run as fast as I can and find a way to hide so that they can't find me..."

Robin turned around and looked at the toilet cubicle deep in the public toilet: "...I know."

He probably guessed why he suddenly came back here.

On the other side, Ling Su grabbed Song Huaimin, dragged him back to the corridor, and then slammed the bedroom door.

In just a dozen seconds, the monster made of flesh and blood grew wildly, occupying most of the bedroom, and even swallowed up the cat-head wall clock and the iron bed.

Song Huaimin was almost slapped in the face by the door that was slammed shut: "Why not just lock it? There's no need to use so much force!?"

Ling Su let go of his hand and ran to the other end of the corridor first: "This monster is too scary, I'm a little scared."

Song Huaimin looked at his expressionless face, which showed no fear at all. He swallowed his words and followed him with big strides: "Why are you still lingering in there? What are you looking for under the bed?"

"Nothing." Ling Su shook his head, "I'm just in case, I'm afraid Robin is hiding under the bed."

Song Huaimin was speechless again: "..."

He still didn't understand why Ling Su wanted to keep Robin, so he could only try his best to keep up with Ling Su's pace, took out his gun and held it in his hand: "It was the same when our group simulated it. A bedroom was suddenly swallowed by a monster, and then the monster started chasing us..."

"This is a cyclic dream, connected from beginning to end, and it will keep repeating if it is not completely resolved." Ling Su nodded, "The people in the dream are trapped, maybe because of this reason."

Ling Su rushed into the nearest public toilet, searched it quickly, and then ran towards the stairs again: "Four o'clock in the afternoon is a critical time node."

Song Huaimin quickly followed and couldn't help asking: "How do you know it's afternoon, what if it's early morning?"

"In most cases, the bedroom appears clearly in the dream instead of other rooms, indicating that the subconscious need for rest and safety is not met."

Ling Su ran to the end of the stairs and turned to the bathroom on this floor: "And we are in that bedroom, the bed is neatly made, which means that even in the dream, this is not a normal rest time."

Ling Su checked the toilet cubicles one by one: "This time node is very clear, not affected by apartment mutations and rapid eye movement sleep period. At four o'clock in the afternoon, the average adult's get off work time is not so fixed. Is it working night shift? Or a student..."

He was still muttering, Song Huaimin suddenly saw outside, his face changed drastically: "Ling Su!"

The speed of the monster was faster than the previous simulation, and it had arrived on this floor at some point.

Several water pipes in the public toilet were wrapped by tentacles and torn off, and the light tubes began to flash non-stop.

It seemed to have swallowed up a lot of rooms, and its huge and bloated body squeezed the tiles on the wall hard, and green juice kept flowing out of the cracks in the wall and the ground.

They were trapped!

Song Huaimin clenched the gun in his hand: "What should we do now?!"

"Calm down." Ling Su avoided the green liquid that was flowing in, "Why don't we... take a shit first!"

Song Huaimin: "Ah? Wait...?"

"Remember to lock it." Ling Su opened the door of a toilet cubicle, pushed Song Huaimin in, and slipped into another one.
