Deja vu
(In French, déjŕ vu means "already seen." and the word déjŕ has an acute accent on the é and a grave accent on the ŕ but we have omitted the accents from the entry term for the sake of the English-speaking search engine.) Déjŕ vu is a disquieting feeling of having been somewhere or done something before, even though one has not. Although most people have experienced this feeling at some time or another, in certain people such sensations of déja vu are part of a seizure or migraine aura; while in others they are the seizure phenomenon itself. See also Jamais vu.
