The strange experience of deja vu sometimes lasts just a matter of milliseconds. Nonetheless it can still catch you off guard and be pretty unsettling. Deja vu means “already seen” in French.

It refers to the sense of having already seen or experienced something you’re confronted with, even though you know that you have never actually seen it before. For example, you visit a new city for the first time in your life, but at a precise moment you get the feeling like you’ve walked down a certain street in the past. According to Psychology Today, it occurs in 60 - 70% of people from time to time, while research suggests more than 97% of us have experienced it at least once in our lives.
