The eerie feeling that you've experienced the exact same situation before, even though you know you haven't. It's that moment when reality feels like a glitch in the matrix, familiar yet impossible.
French déjà vu literally means 'already seen.' The term was coined by French psychic researcher Émile Boirac in 1876, though the phenomenon has puzzled humans for millennia. From French, it entered English in the early 20th century and became one of the most recognized French phrases in English, perhaps because it names such a universally mysterious experience.
Even though we use this word all the time, doesn't it still give you chills? Déjà vu is like catching reality in a hiccup — that moment when your brain insists you've lived this exact moment before, but logic says that's impossible. The French gave us the perfect term for one of consciousness's strangest tricks, and every time it happens, it makes me wonder what other mysteries our minds are hiding from us!
