In Guo Jingming's " The Summer Solstice Has Not Arrived ", he described the feeling of déjà vu. He said that when he walked to a place, he felt familiar for no reason, as if he had been there before. Was it a spiritual legacy from his previous life?

Which chapter is that?
He found it! " Even if you've never been to some places, when you really walk on them, you'll feel that you've been here a few years ago, a dozen years ago, or even decades ago. You've been there, lived there, and touched every corner of every place." However, it didn't feel that short. In the past, he had read books! He felt that there was more to it!
He found it again! " A writer said that this is because the air is filled with the brainwaves left behind by the people who once lived here. Everyone has a different frequency, and the chances of these frequencies being the same are very small. However, there is still a very small probability that the living can receive these brainwaves floating in the air. These brainwaves are 'memory'.
And the person who left behind the brainwaves at the frequency that you just happened to receive is what we once called the previous life."

In Guo Jingming's " The Summer Solstice Has Not Arrived ", he described the feeling of déjà vu. He said that when he walked to a place, he felt that it was familiar for no reason, as if he had been there before. Was it a spiritual legacy from his previous life? This sentence meant that when a person walked to a strange place, he would suddenly feel that this place seemed to have been walked by him before, as if the spirit of his previous life was left in this place. This kind of deja vu is often called hallucination deja vu, and it's a relatively rare phenomenon that may be caused by abnormal activity of certain neurons in the brain. In some cases, this illusion might make people feel very real and even affect people's judgment and perception of the surrounding things.
