Why sometimes what happens in front of my eyes seems to have been experienced before, and it is very

This is called in psychologyDéjà vu (deja vu).

Déjà vu refers to the confusion of the image of the current thing with the appearance obtained when the previous thing is similar but different things, and the re-recognition of the new thing with a sense of familiarity that has already been perceived.

For example, when you meet a stranger, you feel like you've met before, and when you go to a strange place, you feel like you're revisiting the old place.

Normal people also have a sense of déjà vu, but normal people quickly realize that this is a mistake in their memory.

If you don't realize it's a memory error, you have a memory disorder. , another memory error that is different from the sense of déjà vu is oldJamais vu.

The feeling of the old being like the new refers to the feeling of unfamiliarity that has never been perceived and experienced when feeling the old things that have been known for a long time, and the re-admitting mistakes of things that have been experienced in the past have a completely unfamiliar feeling when they are re-experienced.

For example, feeling curious in a familiar environment, seeing people who are very familiar with each other, and feeling that old things are new, is a memory disorder.

I suspect it's me from another parallel world.

Déjà vu. Once or twice a year, I feel like this is weird, I feel like my life is controlled by a force, I can't find out that this kind of thing exists, and I don't know why it's happening.

This condition is known as déjà vu.

The word déjà vu is derived from the French "déjà vu", which can also be translated as "hallucinatory memory", which refers to the sense of déjà vu in an unexperienced event or scene as if experienced at a certain time and place, also known as the hippocampal effect.

Déjà vu is something that exists and has a scientific explanation, and it is not a supernatural event, but a similar scene has appeared in the brain's imagination. In other words, the sense of déjà vu is associated with the brain, which conjures up this picture.

Experiments have shown that déjà vu can easily appear when people are tired, stressed, sick, or surrounded by unfamiliar things, probably because the brain is not able to process the information it receives.

Interestingly, in such cases, there is also a possibility of the opposite of "déjà vu", which refers to the fact that you see a familiar person or thing, but you can't remember the relevant details; Or you may see familiar words but can't recognize them, or words you can't say when they come out of your mouth.

Compared with the elderly, young people are more likely to have "hallucinatory memories"; This may be because young people have a richer life and are often surrounded by new things. Young people also have busier lives and get tired easily, so there are more moments when the brain is "knotted". The frequency of occurrence of déjà vu peaks in early adulthood and slowly declines after the age of 25 years until old age.

The feeling of "this thing seems to have been experienced" may be the memory of a past life.

I also feel this way, I was stunned for a moment when I did a good thing, but I couldn't remember what happened after thinking about it, and it was very uncomfortable, and it happened hundreds of times in the past few years that I felt like I was living in a fake world, but I had nothing to do
