Deja Vu - the sense of vision, in short, deja vu, memory hallucination.
Two-thirds of adults have had at least one "déjà vu" experience.
And people who are more imaginative are more likely to experience strange feelings; people with higher education also experience these feelings more often than others.
Sometimes people don't need real memories at all, and it is possible for the brain to create a familiar feeling on its own.
