Why do you feel deja vu?

Question 1: Why is it sometimes an illusion that people construct shallow consciousness in deja vu scenes? Do you feel that the scene in front of you is extremely familiar? Everything, every detail and even the next scene are as familiar as experienced? However, this is not the case. This is a mysterious and wonderful feeling. According to a recent survey, two-thirds of adults have had this "deja vu" experience at least once.

"The feeling of deja vu will happen to everyone; However, if this feeling is too frequent and too strong, it is a pathological state. " Shen Zheng, a professor and doctoral supervisor in the Department of Psychology of Peking University, said in an exclusive interview with this reporter.

The subjective experience of deja vu is the result of matching memory and perception; It is normal for this to happen occasionally.

"It is normal to have' deja vu' occasionally. This is the result of the interaction between the perception system and the memory system in the human brain. " Professor Shen said.

He told reporters that this should start with the "classification" of perception and memory. Perception and memory are classified in people's minds. Classification process is the basic feature of perception and memory.

According to Professor Shen, perception includes perception of faces, perception of objects and perception of position. Take these three categories as examples. Because their objects are different, we go to a place, the relationship between orientation and space, and the surrounding objects and people may appear at the same time. However, our perception of them is completed by three different functional circuits in the brain, namely, position perception circuit, object perception circuit and face perception circuit. At the same time, these three circuits are located in the second half of the temporal lobe, relatively close to each other.

Similar to perception, memory can be divided into many types. The memory of knowledge and concepts is called semantic memory; Memories of plots, experiences and events, that is, situational memories, and habitual memories formed unconsciously, are all unconscious memories. Each kind of memory can be divided into many small categories.

Because perception and memory are classified, many features of some scenes we have experienced will be stored in different memory systems, but we didn't realize it at that time. When we arrive at a new scene, some parts of the scene may * * * some of our memories and mobilize different memory systems in our brains to match them. At this time, once a certain feature in the scene matches the past experience, there will be a feeling of deja vu.

"This is the reason for the subjective experience of deja vu." Professor Shen said, "It is because people's perception and memory have such a basic feature of' classification' in the brain. Perception activates some contents in memory and matches some characteristics in perception. "

"However, after careful consideration, I have repeatedly confirmed that this is still a new contact scene, not my previous experience. Everyone will have a life experience, because there are many things to remember, and the subjective experience of' deja vu' occasionally is normal. " He said.

The initial understanding of deja vu originated half a century ago, and the medical treatment of epilepsy opened the way for scientists to explore this wonderful experience.

The initial understanding of the subjective experience of deja vu began with medical epilepsy and can be traced back to half a century ago. Professor Shen told reporters that at first "deja vu" attracted the attention of medical scientists and psychologists. Later, according to statistics, normal people will have this kind of subjective experience, and with the accumulation of brain science knowledge, they will gradually reach today's level of understanding.

According to him, more than 50 years ago, Panfield, a professor of neurology at the University of Montreal, Canada, performed brain surgery for epileptic patients to remove epileptic foci or brain tumors. In the process of resection, epilepsy will recur because of less resection, and the normal function of related brain tissue will be destroyed because of more resection; Therefore, in order to ensure the accuracy of the operation, doctors must conduct a health test on the brain tissue around the epileptic focus or tumor before operation, so as to accurately grasp the scope of brain tissue lesions. The doctor looked at the tumor with a probe with weak current and observed how these brain cells would react. Then do the same test on brain cells a little farther away. So, something interesting happened.

This is a 60-year-old man, and the doctor is going to operate on him to remove the temporal lobe tumor. When * * * reaches the surrounding tissue of this tumor, Lao ... >; & gt

Question 2: Why do you feel deja vu? This is the Yu Qian Zhao phenomenon.

Yu Qian Zhao phenomenon, the French original is dé jà vu, and the Chinese translation is "visual sense", which is simply "deja vu". Things or scenes that have not been experienced seem to be deja vu experienced at a certain time and place.

However, the theory to explain this phenomenon in modern science is far from satisfactory. According to the questionnaire survey, two thirds of adults have had at least one "deja vu" experience. And the more imaginative people are, the more likely they are to experience strange feelings; People who travel frequently are more likely to feel deja vu than those who stay at home for a long time; In addition, people with higher education can feel this feeling better than others (perhaps this is because they have experienced unique feelings in Tolstoy or some literary masters). The survey also shows that the incidence of "deja vu" is the highest in youth, and then gradually decreases with age. Especially when people really start to repeat the monotonous life day after day, the incidence decreases. A century ago, when Freud's theory was still the mainstream of leadership psychology research, analysts interpreted "deja vu" as the embodiment of subconscious conflict. But now psychologists have suggested that "deja vu" does not necessarily happen on the basis of deep subconscious conflicts. The average healthy brain will feel this way. Moreover, when people are tired and stressed, it is easy to feel this way. In addition, it may be accompanied by "jamaisvu", that is, when you see familiar things or words, you can't remember anything. Psychologists also point out that the feeling of deja vu may be due to people accepting too much information and not paying attention to its source. Familiarity will come from various channels, some real and some illusory. When you encounter a situation described in the novel that you have forgotten, you may regard it as a memory of your past life. In other words, when you see the real scene of the movie, although you have completely forgotten the movie on the surface, you will still recall thrilling memories in your mind. Psychologists also point out that people sometimes don't need real memories at all, and it is possible to create a familiar feeling inside the brain.

There are several explanations for excluding preconceived so-called scientific views:

1, the human brain is always making up various scenes, mainly subconscious activities. When you encounter a similar scene in reality, it will echo the previously fabricated scene in your memory, and with the psychological strengthening, you will feel deja vu. Because people are sleeping, the brain is still calculating some parameters in reality and getting many results. Deja vu is one of the results of brain operation.

2. Researchers believe that it may be that an impression has been hidden in the dreamer's subconscious for a long time, and then occasionally appears in the dream. Some studies have also pointed out that this phenomenon is related to another subconscious mind that transcends time and space. On the other hand, some brain activity researchers point out that this phenomenon may also be due to the fact that one side of our brain processes information slightly faster than the other.

3. Is this a collision of time tunnels or a memory of a dream? You have seen the scene that will happen in your dream, but you can't remember what happened in your dream, so when it happened, you would feel as if you had experienced it there. In fact, it reminds you of your own memory, the memory of your dreams.

There is another explanation for this in medicine, that is, the phenomenon of instantaneous discharge in cerebral cortex, or false vision, or visual memory, which often happens when you are in a very familiar environment. Our brain has a memory cache. When you see something or encounter something, you first store the memory and then cache it. The reason why what happened in front of us seems to have experienced this feeling is because we made a mistake in memory storage and put it in historical memory. When you look at what happened in front of you, you find it out from the historical memory, and you feel as if it had happened before. This illusion is more likely to occur when the brain is tired.

5. The difference of stream of consciousness between life and death. Death/\ life \ _ _ _/death. This is a moving picture of human consciousness. People are born with consciousness, and this consciousness has been advection until death. After death, consciousness will follow a tortuous route back to birth, and so on. Because of the tortuous route after death, the memory of life is recorded in segments, and only the memory of contact point can be entangled with the consciousness of the next "life", and the phenomenon of deja vu will appear.

Question 3: Why do people feel deja vu? Will the "soul" travel through time and space? Scientists reveal the illusion of memory

I'm afraid everyone will encounter a strange feeling of sudden germination in their life. When you look at something,

I will suddenly realize that such a thing happened once. I have been there, done such a thing, and heard such words. At that time, the light was like this ... At that moment, the brain sent us a signal indicating that it was aware of what happened. This phenomenon is called memory illusion, also called memory illusion. How can people have memories of the future?

The manifestations of memory hallucinations are mostly too bizarre to explain.

Since ancient Greece, more than 1000 stories have been recorded in chronicles, chronicles, philosophy and literary works, all of which say that some people suddenly feel that they have become another person, or that they have reached another era, and they often quote many details that they don't even know. Because it never happened, but they found and described this strange phenomenon. 1900 French doctor Florence? Arnault also named it the memory illusion. He also concluded that this phenomenon not only exists in vision, but also appears in the form of auditory illusion, reading illusion and experience illusion.

The manifestations of memory hallucinations are mostly too bizarre to explain. For example, some people believe in dreams that foretell good or bad. According to superstitious people, it is their souls who travel back to the past regularly, so they have seen and experienced everything. And after a few days or even years, when their dreams come true, they will be surprised to "recognize" this strange situation. Foresight has therefore become a memory. Some people also blame these on the "ancestral memory" passed down from generation to generation under the influence of strong emotions.

For those who agree with the theory of reincarnation, the illusion of memory is also evidence that they have had past lives.

Many people believe in reincarnation theory, including some scientists and philosophers. For example, Pythagoras thought he might have been a shepherd in his previous life. Sylvester Staro thinks that he was a sentry of a nomadic tribe in his previous life. Gianu? Livz, according to her, was a dancer in a temple in Bangkok in her last life. Their memory hallucinations were confirmed by hypnosis, which brought them back to the past.

The famous Swiss psychologist and philosopher Carl? Gustav. Jung first felt this way when he was 12 years old. From then on, he firmly believed that he was living another life at the same time, sometimes in the18th century.

Jack. London and Conan Doyle also described the plot of memory illusion. The comedy Magic, starring Sulika, is exactly the opposite of the illusion of memory, that is to say, it is a completely experienced sense of reality. I remember when the protagonist was preparing for the exam and looking for an outline in the street, there was a girl standing next to him. Being addicted to reading, he didn't find himself in her home. But then I went to her house when I was "conscious" and suddenly remembered it.

Russian researchers began to use holography to explain the secret of memory illusion.

Leonid, a researcher and associate professor of philosophy at the highest school of humanities of the Russian National Humanities University? Karashev has his own unique ideas. He said that many scholars believe that the memory illusion stems from excessive fatigue and brain confusion, so they regard the unknown as known, but he tends to think that this is a "holographic illusion."

In his view, the principle of so-called holography is that any part of a photo can reproduce all the information of the original photo. In other words, tearing a photo into pieces, as long as there is one piece, can restore the overall image of the original photo. The so-called "holography" means that all information is contained locally. The strange phenomenon of memory hallucination is probably formed in a similar way. In fact, all the information we always come into contact with in our lives is stored in the form of codes in our brains, but what we see and hear is deeply hidden in our subconscious. As long as anything happens, these messages will pop up, such as what smells, sounds, lights, and similar scenes will induce us to have an illusion, as if there was a similar situation 5- 10 years ago. Although if carefully analyzed, there are still many differences.

Karasyev also believes that teenagers aged 65,438+07 are most prone to memory illusion, because they have little experience and are quite sensitive to various living conditions. When you are 35-40 years old, you will be hit by the illusion of memory for the second time ... >>

Question 4: Why do some people feel deja vu when they see some pictures? This is the Yu Qian Zhao phenomenon (Yu Qian Zhao is a French word with a familiar pronunciation). Chinese translation is "visual sense", which refers to things or scenes that have never been experienced, as if they had been experienced at a certain time and place.

This is a common psychological phenomenon. According to the survey, two thirds of adults have had at least one experience. The survey also shows that the incidence of "deja vu" is the highest in youth, and then gradually decreases with age.

As far as its achievement is concerned, there is a great debate at present. A century ago, analysts interpreted "deja vu" as the embodiment of subconscious conflict. But now psychologists have suggested that "deja vu" does not necessarily happen on the basis of deep subconscious conflicts. The average healthy brain will feel this way. Moreover, when people are tired and stressed, it is easy to feel this way.

Psychologists also point out that people sometimes don't need real memories at all, and it is possible to create a familiar feeling inside the brain.

Question 5: Why do people feel deja vu when doing things? Yu Qian Zhao phenomenon, the French original is dé jà vu, and the Chinese translation is "visual sense", which is simply "deja vu". Things or scenes that have not been experienced seem to be deja vu experienced at a certain time and place.

However, the theory to explain this phenomenon in modern science is far from satisfactory. According to the questionnaire survey, two thirds of adults have had at least one "deja vu" experience.

As for why young people and old people have this phenomenon, it is also easy to explain. The normal ideology of young people is still forming, while the brain of the elderly has a strong memory function. And ... >>

Question 6: Why do we sometimes feel deja vu? There are two possibilities. Actually, it's just a joke played by the brain. The connection between neurons in the brain is realized by electric current. But sometimes these currents suddenly slow down or stop for a thousandth of a second. This has certain influence on the normal operation of the brain. For example, if this happens to your brain when you are doing something, your brain will intuitively find this breakpoint, and often the result is no answer. So, it was when we found out the answer that we felt as if something made us feel deja vu. In fact, it is just a form of temporary forgetting! Second, it's probably a dream situation, but in reality you just met it. This is also a reason. When you sleep at night, you are in a deep sleep, so you are dreaming, no matter what the situation is. However, there are not necessarily a few dreams that we can remember, or even none. However, they still exist in our brains, only in the' deep' subconscious. I think most of our deja vu comes from dreams we don't remember, but after all, it is deep in our brains (that is, we can't remember whether it is a dream or not), which makes us feel that we have had it before.

Question 7: Why do people feel deja vu? In our life, there are always some things that make us feel deja vu, sometimes for a moment. I have experienced this kind of environment and scene before. Why do you feel this way?

According to previous statistical research, people can predict thousands of small events every day, whether it is feeling whether the bus arrives at the station, who will knock at the door, or feeling that the cup may slip and break.

Now, scientists are beginning to reveal why the brain makes such amazing predictions, just like fortune tellers, but these magical predictions are suitable for more ordinary things in daily life.

Human beings' prediction of the future is related to mysterious substances in the brain. Researchers at Washington University in St. Louis are now focusing on the midbrain dopamine system, which is thought to provide some kind of signal to the rest area of the brain when some events suddenly occur.

A premonition of thousands of small events in our daily life, such as waiting for the bus to arrive at the station, is sometimes felt in advance. Researchers believe that these tiny premonition abilities stem from something in our brain. How does the brain produce these fortune-telling abilities?

Using magnetic resonance imaging (MRI), researchers found that the dopamine system in the midbrain would appear similar coding behavior in upcoming daily events and predict possible errors. The research results show that in the process of a daily event, when the event stops at a certain moment, people's prediction accuracy is as high as 80%-90%.

In other words, it is impossible for human beings to meet something they have never seen before. In order to prevent some accidents, our brains will rehearse these situations. This part of the rehearsal will be stored in an unknown area of the brain, and when we encounter similar events, we will get a response plan. In short, this is a mechanism for us to protect ourselves for countless years!

Question 8: Why do people feel deja vu because of parallel universes?

Question 9: Why do you feel deja vu for some people? Rationally speaking: people have two eyes, a nose and a mouth, and it is not impossible to grow into a feeling of deja vu occasionally! Hehe, because what is said upstairs is already very romantic, so I'll stick to the cliche!

Question 10: Why do people feel deja vu? The reason of deja vu may be that they passed by somewhere and lacked a chance to get to know each other. When the opportunity comes, you will find that this person seems to have met somewhere. Deja vu may be the fate of past lives, but this life is the fate of acquaintance. Deja vu may be more congenial, finding that this person seems so similar to himself at a certain stage.
