Chen Ge didn't understand Dr. Gao's text message: "Why is washing hair related to self-protection?" ”

"The premise of traumatic stress disorder is that he has been hurt in some way, and Mennan has repeatedly washed his hair many times in reality, most likely to get rid of some kind of psychological shadow, which may be related to his past experience."

"Ever experienced?"

"That's right, the experience left a strong psychological impact on him, every time he recalled, or encountered something similar, saw something similar, his body reacted, and in order to relieve the pain, he instinctively looked for ways to comfort himself. As it stands, this method is to wash your hair. After a while, Dr. Gao sent another text message: "When I first entered the school, I asked Mennan why he wanted to major in psychology, and the answer given by this kid was that he wanted to treat someone. If you think about it, the person he is talking about should be himself. ”

"It seems that the root of the problem is still in Mennan's childhood, I feel it is necessary to make it clear to him, only by knowing the cause and effect, can we help him."

"If my speculation is true, then I can't even ask him. He'd been trying his best to avoid it, and now that he remembered it little by little, I'm afraid he would lose the irritation and collapse completely. ”

"Then we will contact his family, the child is in such pain, and the parents don't care, it's too much to say." Chen Ge really wanted to take a photo of Mennan's current appearance and send it to his parents so that they could see it.

"I already asked when I called some time ago, Mennan has had a quirk of washing his hair since he was a child, and his parents are used to it and don't think it's such a serious thing."

"Didn't they say what caused this fetish?"

"No, when Mennan was very young, his parents took him to see a psychiatrist, and the diagnosis at that time was obsessive-compulsive disorder. This was very rare at his age, and considering that the child was still young, he was not given the appropriate medication, and the doctor only encouraged his parents to give him more company. ”

"Apparently his parents didn't listen to the doctors." Chen Ge replied without thinking about it, if Mennan's parents really cared about him, their attitude would not be so cold.

"Mild OCD doesn't affect his life, so his parents haven't paid attention to it. In addition, after careful inquiry, I learned that Mennan's biological mother was killed when he was five or six years old, and that his father later reorganized the family, and Mennan also had a younger brother. ”

"Biological mother killed? Is there such a thing? Chen Ge felt that the already blocked road had a new exit.

"The relationship between his biological parents is very bad, his father is away all the year round, and his mother leads the child alone. One day the thief entered their house, and then what happened later, Mennan's current parents don't know, only know that the neighbor called the police the day after the crime. ”

"The day after the crime?" Chen Ge's heart jumped: "Where was Mennan at the time of the crime?" ”

"I don't know where Mennan was at the time of the crime, but I know that when the neighbor called the police, Mennan was at the scene of the crime, and he was the first to find his mother."

Looking at the text message sent by Dr. Gao, Chen Ge felt a chill slowly rising down his back: "So Mennan and his mother stayed at the scene of the crime for a day and a night?" It wasn't found until the next day, was it? ”

It can be understood that maybe the gangsters let Mennan go, or maybe he happened to be not at home at the time, in short, Mennan escaped by luck. But seeing this scene at a young age must have had a great impact on his psyche, and I suspect that his obsessive-compulsive disorder and current illness are related to this murder when he was a child. It's just that I can't understand why he keeps washing his hair, and is there any connection between washing his hair and murder? ”

The doubts revealed in Dr. Gao's text message were exactly what Chen Ge wanted to know, he stood in front of the mirror and looked at himself in the mirror.

"Washing your hair? Self-behavior protection? ”

The scene when he imitated Mennan just now flashed in his mind, Chen Ge touched the back of his neck, and suddenly thought of something: "Water droplets!" ”

He immediately sent a text message to Dr. Gao: "At the scene of the crime, where was Mennan's mother's body found?" ”

"After the gangsters accidentally killed the mother of the door panel, they removed the moisture-proof board on the top of the bathroom and stuffed it in. If it weren't for the neighbor's children and Mennan who often went to school together, the relationship between the two families was very good, and they would not have noticed the problem so quickly. ”

"Moisture barrier on top of the bathroom?" Chen Ge looked up at the bathroom where he was, the apartment was very low, and it was very depressing to live in: "I think I understand why Mennan has obsessive-compulsive disorder to wash his hair." ”

He took out his mobile phone and texted Dr. Gao back: "You see if this will happen, after the thief entered the house, both mother and son found the thief." The mother asked Mennan to hide and secretly called the police herself, only to be discovered by the thief. ”

"It's possible, but what does it have to do with shampooing?"

Mennan watched his mother being killed and hiding her body, and after the gangsters left, he went to look for his mother. When he came to the bathroom, his mother's blood was dripping right on the top of his head. When Chen Ge typed these words, he felt a little uncomfortable: "So until now, as long as there is liquid dripping on Mennan's head, or recalling the scene at that time, he will wash his hair over and over again, wanting to forget those memories." Doctor Gao, what you said before is so right, Mennan is definitely not an ordinary obsessive-compulsive disorder! ”

After sending these words, Chen Ge looked outside the house, Dr. Gao in the bedroom had a shocked expression, and also looked at Chen Ge in the bathroom at the same time, and the two looked at each other very tacitly.

"The cause has been found!" Dr. Gao directly put away his mobile phone and walked towards Chen Ge: "I'll take him away and carry out the corresponding trauma disorder treatment." ”

"I'm afraid not." Chen Ge looked at Mennan who was standing in place and shook his head slightly: "In that dream that Mennan kept repeating, washing his hair was not terrible, what really scared him was the man who was getting closer and closer. To help Mennan, we need to find out everything about that man and get him out of Mennan's dreams. ”

"Get rid of the things in your dreams?" Doctor Gao's face was strange, he looked at Chen Ge, and then looked back at Mennan, who was standing in a strange posture, and felt like he had entered a mental hospital for the first time: "You're not joking with me?" ”

"I already have a rough guess, and I can get it verified tonight!" Chen Ge connected all the clues, and he was sixty percent sure in his heart: "There are indeed three 'people' in this room, and the identities of the two 'people' can be determined, as long as another person is found." ”
