Xu Feihu has been in the villa for more than ten days, eating, drinking and behaving in the villa, behaving quite strangely, no one knows what he is fantasizing in his mind, at this time, it seems that only he knows what kind of encounter he is experiencing.

"Doctor, why do people suffer from mental illness? Why do psychopaths have bizarre fantasies? Huo Xiaotian asked strangely.

He really couldn't figure out why the human brain would conjure up all sorts of non-existent scenes, where did this imagination come from, and whether there was some more mysterious force behind it that dominated the human brain.

After hearing Huo Xiaotian's inquiry, the psychiatrist shook his head with a smile: "Actually, people have fantasies, such as dreaming when they sleep, sometimes they dream of some strange things, some things may have been experienced in reality, and some things have not been experienced, which are all related to our brain activity."

Our brain, in fact, is a perceptual organ, the earliest invertebrates did not have a brain, their bodies only have some sporadic nerve cells, they can only feel some local stimuli, but can not feel light, sound and objects, even taste, and then with the evolution of some of these invertebrates, gradually evolved out of the vertebrae, nerve cells converge in the vertebrae, become the earliest spinal cord, and later, the spinal cord slowly evolved into the brain, This can be said to be a milestone in biological evolution.

In other words, when living beings had not yet evolved brains, in fact, they were no different from machines, because they had no perception and no self-awareness. It's just the genetic material of DNA that is used to carry out the genetic program. And when the brain evolved. These creatures began to awaken to themselves, realizing that they were living beings, and gradually evolved their senses such as taste, hearing, and sight.

With the evolution of sensory organs and the development of nerve cells, the brain receives more and more stimuli and needs to process more and more information. Such a huge amount of information is stored in the brain, which will make the brain unbearable, so we need eight to ten hours a day to rest, in fact, to put it bluntly, let the brain rest.

During sleep, the active self-consciousness is turned off, and the subconscious mind of the brain begins to play a role, and this subconscious of the brain is called the homing response in our academic studies, which is the process of our body as a biological machine in the execution of genetic programs.

When the subconscious mind comes into play, it leaves a little mark on our cerebral cortex. These marks trigger certain chemical reactions in our cerebral cortex that allow us to wake up later. There is the illusion that you are dreaming about something, in fact, you are not dreaming about anything, but when the subconscious mind is working, it stimulates some memory fragments in your cerebral cortex.

Of course, sometimes people will rejuvenate their active consciousness again in their sleep, but this active consciousness is very weak, but it will trigger some memory responses under the action of the subconscious, and this memory response will follow the active consciousness to recall, this process often makes people feel as if they have changed their dreams by their own control, in fact, it is also a wrong understanding.

Generally speaking, our human evolution so far, is not considered to be a very perfect evolution, dreaming is a big flaw, because dreams have no practical significance for our human life, reproduction and evolution, I believe that with the progress of evolution, our brain will become more and more perfect, and I also believe that our brain will evolve more powerful functions in the future, but one thing you need to know is that the world we see and hear may not be real, Because this is a chemical reaction of our brain to external stimuli, or the brain's own 'imagination', which may be very different from the real world.

Normal people will control the fantasy function of the brain and focus their attention on the aspects that need to obtain information, while psychopaths often lack attention and lack the ability to control the brain, so the brain often has some bizarre fantasies, these fantasies are not controlled, so it is difficult for us normal people to understand what they are fantasizing.

Even if it is the same psychopath, the thoughts of this second and the next second may be very different, their brain thinking is jumpy, just like we are in an unconscious dream, I don't know what we will dream, this is also so far, human beings have not completely solved the key to psychiatric diseases, this seems to be a defect in our brain, I am afraid that for a long time, it cannot be completely solved. The spiritual expert patiently explained to Huo Xiaotian from a professional level.

After listening to the expert's explanation, Huo Xiaotian suddenly felt that he benefited a lot, it turned out that dreaming could not predict the future good fortune and misfortune, it was just a self-reaction of the brain.

"Doctor, how long is he going to have to stay inside before he can come out?" Huo Xiaotian asked.

"It's hard to say, since you have used this kind of stimulation therapy, I think it is better to just go through it to the end, maybe there will be a miracle?

If he can realize that he is fantasizing, it proves that he still has the possibility of recovery, and if he has been immersed in his fantasies, I am afraid it will be difficult to have any hope of recovery. The expert said.

"So what am I going to do?" Huo Xiaotian asked again.

"Pay attention to his safety, just add some food and water to him regularly, by the way, when entering the villa, remember not to disturb him, otherwise it may seriously irritate him, which will cause dangerous things to happen." The expert kindly reminded.

"Okay, thank you, doctor." Huo Xiaotian thanked with a smile, and at the same time took out a thick envelope from his arms and handed it to the doctor, "This is a little bit of my heart, please don't shirk the doctor." ”

The doctor hurriedly waved his hand, "Mr. Huo, no, I can't accept it." ”

"Doctor, this is not a red envelope, it is a little bit of my heart, you have stayed here for so many days for my brother's illness, so dedicated, if I don't express it, I can't say it in my heart, you can take it." Huo Xiaotian forcibly stuffed the envelope into the doctor's briefcase.

Seeing Huo Xiaotian like this, the doctor had no choice but to reluctantly agree.

"Okay, then I'll go back, if you have something, feel free to call me, this is Director Chen's phone, if I'm not there, you can contact him, another expert doctor in our psychiatric department." The doctor handed a business card to Huo Xiaotian with both hands, Huo Xiaotian took the business card, smiled and nodded.

"Okay, Dr. Sun, go slowly." Huo Xiaotian personally sent Dr. Sun out of the tent. (To be continued......)
