Story and comic created by CCFamily.
"Déjà vu" is a French phrase meaning "already seen". It refers to the experience of feeling familiar with a situation or something which actually has not happened or appeared before.
Many people have this feeling at least once in their lifetime. However, scientists still cannot explain the reason of this "déjà vu" experience. It is often said that this is a feeling related to what we have encountered in dreams.
