The feeling of déjà vu is a very wonderful feeling. Many people think it is the key to the door of the memory warehouse in the past life, while others think it is a cause of epilepsy.

Some people think that it belongs to multidimensional space and parallel universes. But there are many different opinions on why, and there is no consensus.

Su Yu couldn't figure it out for a moment, and involuntarily thought of various analyses and speculations about the sense of déjà, trying to get some inspiration from it and find out the source of why he had such a strange feeling about Zhao Xiaoai.

According to scientists in the old era, this feeling is the result of the interaction between the perceptual system and the memory system in people's brain.

If a person wants to understand why the feeling of "daily déjà vu" appears, he should start from the classification of perception and memory.

Classifying the things you come into contact with is a basic feature of perception and a basic feature of memory.

A person's perception includes perception of time, perception of space and perception of objects in it, etc.

Because the objects of these three perceptuals are different, when humans arrive at a place, the direction and space relationship, surrounding objects and figures may appear at the same time.

In other words, these things poured into the human cerebral cortex at the same time.

However, human perception of them is completed by three different circuits in the brain. Similarly, human memory has become three categories, rather than one united.

In other words, when we see something, we see its whole, but in our brains, it cuts the thing into parts and stores it separately.

Wait until we need memories, and put them together again.

Therefore, human memory is also divided into many types, including episodic memory and semantic memory.

Episode memory is prone to a sense of déjà vu, which makes people feel familiar, as if they have come to a place in their previous life. And in this life, when they come to this place again, they think that some of the memories of the previous life have been revived.

Semantic memory is about memory of knowledge and gratitude. What a person learns when he is in school, as well as organized knowledge about rules, formulas and algorithms that operate these symbols, concepts and relationships, etc., can all belong to semantic memory.

The organization of semantic memory is abstract and general. The information it contains is not limited by the specific time and space of the received information, and is referenced by meaning. Therefore, compared with episodic memory, semantic memory is often less disturbed, and it extracts information faster and does not even require search.

Therefore, semantic memory rarely has a sense of confusion. Even if a person cannot remember a concept or distinguish several formulas. However, when he sees these formulas and concepts, he can still know when and where he has learned these concepts. He knows that he has indeed come into contact with these concepts and formulas, so he basically does not have a sense of déjà vu.

However, episodic memory is different. Episodic memory is the memory of events or scenarios that occur at a certain time and place.

It is a memory of plot, experience, and events, and is often unconscious memory.

This memory time and space are coordinates, involving specific events in a personal life. The information it receives and maintains is always related to a specific time and place, and is referenced by the personal experience.

Therefore, episodic memory is more susceptible to interference than semantic memory, and information is extracted slowly, which often requires hard work to search.

Each type of memory can be divided into many subcategories. Precisely because perception and memory are "classified", many characteristics of some scenes that have been experienced will be stored in different memory systems, but this person himself cannot realize it.

When this person walks into a new scene, some parts of the scene may sting some of his memories, mobilize different memory systems in the brain and match them. Once a certain feature in the scene matches past experiences, a "dai" feeling will be created.

Everyone will have their own life experiences. Because there are a lot of things accumulated in the past unconsciously, it is normal for the occasional subjective experience of "daily vu".

But Su Yu did not think that the feeling of déjà vu between him and Zhao Xiaoai came from some fragmentary memories of the past.

He just found a familiar smell in Zhao Xiaoai, but he couldn't remember what it was.

This is very similar to some patients with amnesia and epilepsy.

It is particularly difficult for people with amnesia to recall specific situations, but they can have a general recollection of it.

If the patient recalls the scenery of a place he had been to, he said that he remembers that there were flowers, and the flowers bloomed on the trees. But he could not tell the characteristics of any specific flowers, nor could he tell what he saw and felt during any specific trip.

Therefore, when they see many flowers, they will feel familiar. But they can't tell when or where they have seen this flower.

But Su Yu knew that he was not an amnesia patient. Because of the existence of the gold-eating body and the evolution of the brain, Su Yu not only did not forget it, but could also extract everything he had experienced in the past and restore it in his mind in three-dimensional images.

Therefore, he had never seen Zhao Xiaoai forget it again.

Epilepsy and madness are mainly manifested as mental disorders, with basic characteristics of movement disorders, emotional disorders, hallucinations and disorders of consciousness.

In this case, it is not a difficult problem to experience a sense of memory confusion.

But Su Yu also doesn't think he has epilepsy.

So he was a little incomprehensible about Zhao Xiaoai's extreme familiarity.

This is not a question of looking at one person like another, it is a strong feeling similarity. Moreover, this similarity is similar to Su Yu, which leads to Su Yu having a strange feeling of seeing himself in another time and space.

"The ground is dark, there is something strange, I need to tell you!"

"What's the matter?" asked lazily in Su Yu's body, lazily in the hot spring space.

"That's right, I met a person. This person gave me a strange feeling, as if he was my brother, connected to my bloodline. However, I felt that this person was more like another self standing there!"

"What, did you see yourself in another time and space? Is there such a thing?" The darkness on the ground suddenly jumped out of the hot spring, and the slap of water splashed high...ro!.
