Mennan didn't dare to fall asleep, and stubbornly stood in the middle of the room. He remained in an eerie position, his head as if it was about to be pressed off his shoulder.

"I always felt like he had something on top of his head." Chen Ge was afraid of stimulating Mennan, and his voice was very low: "It's not the kind of psychological fantasy, but something that really exists." ”

Dr. Gao waved his hand lightly, and accompanied Mennan, he took out his mobile phone, as if he was texting someone.

Seeing that Dr. Gao did not reply, Chen Ge began to search the other rooms in the rental house again.

The house is only about 30 square meters, but the sparrow is small and has all kinds of organs, including a bedroom, a living room and a separate bathroom.

"It's just a very ordinary rental house." Chen Ge turned around and didn't find any dead ends, and there was no possibility of hiding the corpse at all.

He came out of the living room and pushed open the wooden door of the bathroom, and to his surprise, a bust mirror hung on the wall facing the door.

"Mirror to door?" Because of the first nightmare mission, Chen Ge is very sensitive to mirrors.

He silently walked to the mirror and looked at himself in the mirror: "A rare layout, as soon as you open the door, you will see yourself in the mirror, it will feel a little strange." ”

The mirror surface is very clean, it seems to be wiped frequently, and there is no trace of smudge.

Looking away, there was a washstand under the mirror, where he had been standing and washing his hair in Mennan's nightmare.

Chen Ge imitated Mennan's posture, lying in front of the washstand, his body bent forward ninety-five degrees, and his head just reached under the faucet.

"From this angle, he can see the scene outside the house, and it is entirely possible that the scene he dreamed of in his dreams will come true." If you lie under the faucet and can't see the scene in the living room, or if your vision is blocked by other things, then Chen Ge won't feel scared, which means that it's just a dream.

But after his own experiments, he found that all this is completely possible even in reality.

Sticking your head into the sink, the world is turned upside down.

Mennan said that every time he dreamed, the man would get closer to him, and this place was also very suspicious, why didn't the other party just come over and kill him? If you have to torture him little by little, do you have any deep hatred between the two? Chen Ge was thinking about it, and the back of his neck suddenly felt a little cold, and he immediately straightened up and touched his neck.

"A drop of water? Where did it drip? Chen Ge looked up at the roof, there was no trace of water seepage on the ceiling, and the drop of water appeared inexplicably.

"Is it a mirror?" He couldn't help but think of himself washing his hair in front of the sink, and in the mirror he leaned out half of his body and grabbed him by the neck.

"The black phone shows that the name of this trial mission is called the room of three people, and the mission name itself is a hidden hint." Chen Ge looked at himself in the mirror and felt as if he had guessed something: "There are three 'people' in the room, Mennan counts as one, and the man who keeps approaching in the dream counts as the other one, and at this time there is a third 'person' in the room, will this third person be hidden in the mirror?" ”

Chen Ge propped up the sink with both hands and glanced to both sides, and he found two empty shampoo bottles thrown in the toilet trash can.

"How long has it been since Mennan moved to this apartment building and he has already used up two bottles of shampoo? If he just washes his hair in a dream, how can there be less shampoo in reality? Could it be that this child has a habit of sleepwalking? Will he run alone to wash his hair on the big night? Chen Ge thought for a while and felt that it was unlikely, when he communicated with Dr. Gao before, the other party said. In order to rule out the reason for the apartment itself, Dr. Gao took Mennan back to his home, but Mennan's nightmare did not stop.

"Sleepwalking is ruled out for the time being, but if Mennan used up two bottles of shampoo in a short period of time when he was awake, this is even more strange, why did he wash his hair like crazy?"

No matter how clean people are, it will be good to wash once a day, but Mennan has used up two bottles of shampoo in a short time, and the third bottle of shampoo next to the sink is only half a bottle.

"Under what circumstances do people wash their hair all the time? Itchy head? Dirty hair? Or feel like something in your hair? Chen Ge leaned against the wall and thought: "Mennan fought with people twice at school, the first time because he found that the animal patterns on the curtains were asymmetrical, and the second time because he couldn't count the sesame seeds on the pie, this person should have a severe obsessive-compulsive disorder." ”

For a person with obsessive-compulsive disorder, if there is a slight mistake, they will try to correct it, and if they can't correct it, they will feel uncomfortable. Chen Ge felt that Mennan was crazy about washing her hair, and it was also for this reason.

"The answer to the question is only clear to Mennan himself, and he probably has hidden something very important from Dr. Gao." Chen Ge was speculating here when the mobile phone suddenly vibrate, and when he took it out, it turned out to be a text message from Dr. Gao.

"Mennan's family environment is a bit complicated, and the results of my previous investigation are not quite the same. After I told his family about Mennan's illness, his family reacted very coldly, just saying that they would pay enough for Mennan's bank card for treatment, and had no intention of visiting him in Jiujiang. It's inconvenient for me to let Mennan know about this, so I can only send you a text message to tell you. ”

"My son is sick? Parents don't want to come and accompany them? ”

"I didn't expect that when I asked Mennan and his classmates before, everyone felt that Mennan was born in a very harmonious family, and I also deliberately looked through his social platform, which has a lot of articles on gratitude to the family."

Mennan shows outsiders that he is a good student who lives in a warm family, is well-educated, has a cheerful personality, and has a solid major, but in fact, all this may be just his disguise.

After reading the text message, Chen Ge told Dr. Gao what he had just discovered.

It didn't take long for Dr. Gao to reply to several text messages.

"OCD can be roughly divided into four categories: worry, ritual, cleanliness, and perfection, and after my observation, Mennan's condition does not belong to any of these four categories, and it seems that he only washes his hair because of this need."

"In my opinion, Mennan's performance is more like another kind of mental illness - traumatic stress disorder, for example, after an earthquake, individual survivors will be in a state of high alert for a long time, they will have a hard time getting rid of the shadow of the earthquake, and the brain will give them a false message, as if the earthquake will recur at any time."

Mennan's symptoms are very similar to traumatic stress disorder, his nerves are tense and his eyes are rolling, which means that he is very insecure, as if something will come out and hurt him at any time. In this case, he went to wash his hair, which may be an act of self-preservation. ”
