Why do people sometimes feel that this scene has ever appeared?

The hippocampal effect（hippocampal effect）。

Déjà vu", also known as "déjà vu", is a physiological phenomenon that refers to the déjà vu of an unexperienced event or scene at a certain moment in which it is called, also known as the "hippocampal effect".

Questionnaires. It shows that two-thirds of adults have had at least one "déjà vu" experience, and that the more imaginative people are, the more likely they are to experience strange feelings;People who travel all year round are more likely to experience "déjà vu" than those who stay at home for long periods of timeHighly educated.

The survey also found that the incidence of "déjà vu" is highest in youth, and then gradually decreases with age. It is especially less common when people start to live a monotonous life day after day.

Analysts interpret "déjà vu" as the subconscious.

When people are tired or stressed, they tend to feel this way.

Psychologists believe that the emergence of "déjà vu" is mainly due to the fact that people receive a lot of information from the outside world and do not pay attention to the information. Familiarity enters the brain through a variety of channels, some of which are real and some of which are illusory.

Stream of consciousness. Columbia University, USA.

According to research by psychologist Alan, about 60% of the world's population experiences this wonderful feeling, but it gradually declines with age.

This is due to the normal ideology of young people.

In the process of formation, the brain memory repetition function of the elderly is stronger.

Consciousness is a high-level mental activity unique to human beings, which mainly refers to the individual's awareness of the changes in his inner physical and mental state and the people, things, and things in the surrounding environment by using feelings, perceptions, thinking, and memory.

Our memories are constantly storing what we are aware of, and when we are in a familiar environment, our brain responds to this phenomenon in a timely manner, giving us a sense of déjà vu.

Refer to the above content: Encyclopedia - Hippocampal Effect.

When you encounter a similar scene in reality, it will echo the previous brain fictional scene in your memory, plus the effect of psychological reinforcement, you will have a sense of déjà vu. Because people are sleeping, the brain is still operating on some parameters in reality, and many kinds of results are obtained.

Researchers believe that an impression may have been hidden in the dreamer's subconscious and then manifested in the dream by accident, and some studies have suggested that this phenomenon is related to another subconscious that transcends time and space.

This is also the collision of time and space tunnels or the memory of a dream, in which I have seen the scene that is going to happen, but I can't remember the dream clearly, so when you encounter something that happens, you feel as if you have been there. In fact, it evokes your own memory, the memory of dreams.

This is a psychological phenomenon called the "visual phenomenon".

Check the wikipedia, the introduction is very simple, only one sentence, as follows:

Immediacy: The sense of déjà vu in something or scene that has not been experienced before, as if experienced at a certain time and place.

People will encounter many things in their lives, and the plots are very similar.

I don't know, I used to have this feeling, like the same dream, when a certain scene comes out, my brain will unconsciously extract the scene I experienced before and restore the scene. And it's very real.

According to the analysis of scientists......It's called the sixth sense....Or rather, out-of-body ......

One is that people like to be nostalgic. Many times, I always think that I have forgotten the past, but I remember it; Many times, I always say to myself that I don't love anymore, but my heart hurts faintly; It shows that the love is still there, and the scene will be repeated!

There is also a situation where you have had some dreams before, and then it happens one day, and the scene is almost the same. This seems to be the truth of thinking during the day and dreaming at night!

The reasons for this state of BAI are as follows

At this time, experience zhi

The scene once appeared in someone's dream, and it is equivalent to restoring the scene in the dream when it belongs;

A long time ago, someone experienced a similar scene to the present, but it was difficult to remember it due to the precipitation of time, and now it is possible to recall the previous memories when encountering it again;

When someone is chatting with someone and hears someone describe a similar scene to themselves, this memory is kept in their minds, and when someone encounters it in person, it will also feel familiar;

It could also be a delusion on someone's part.

I feel the same way, so inexplicable, hey.

This feeling is called déjà vu, and it is the feeling that a human being in a real environment (as opposed to a dream) suddenly feels that he or she has "experienced something in a certain place". According to most people's recollections, it is as if they have seen a certain scene in a dream, but have forgotten it, and when they encounter it in reality, a feeling of "déjà vu" emerges.

The following is a list of all possible causes of the perception of déjà vu, the true cause of which has not yet been proven.

When we encounter a situation similar to a past experience, the neurons in the brain that process the past experience may simultaneously generate impulses, creating a sense of déjà vu.

Because the human brain is aware of things that have not happened in the short future.

It is a person's perception of what is happening in the same timeline of other multiverses.

Due to brain processing errors, the information in front of you is mistakenly regarded or judged as a "picture in memory".

From a medical point of view, the cause is due to a sudden mismatch in the processing of information from the left and right brains.

During the course of several seconds of vision, it is an illusion to mistake what was seen a few milliseconds ago as something that has been seen in the past.

That's what the university asked. Professional scientists and Buddhists have studied this phenomenon for a long time. Scientists say that it belongs to the human subconscious.

Buddhism is called supernatural powers. The scene or event that you feel is transmitted to your brain cells by the deep consciousness in your brain at a certain nerve. Then produce sight and hearing, as well as memory.

After a long period of time, the phenomenon of occasional recurrence.
