Why did people always have a feeling of deja vu about certain things?

And I've never experienced that thing or that scene

Answer 1

The reason why people always had a feeling of deja vu was because there was a mechanism called "pattern matching" in the brain. This mechanism can help us quickly identify information that is similar to what we remember, allowing us to feel a sense of foreknowledge in certain situations.

There is an organ in the human brain called the " hippocampi " that helps us remember long-term information, including past experiences and dreams. When we experience a similar scene or plot, our brains will try to match this information with the existing memories of the hippocampus-to create a feeling of deja vu.

Our brains also generate certain patterns based on the current situation and environment. These patterns can help us quickly identify and remember similar information. For example, when we look at a picture, our brain will generate certain neural pathways that allow us to quickly recognize the picture.

Although we feel that we've seen each other before, in fact, this feeling is not necessarily accurate. This feeling may be due to the deviation in the processing of information in our brains or because there are some confusion and errors in our memory of this information. So when we encounter something unfamiliar, we still have this feeling.
