paramnesia

n. distortion of the memory, falsification of the memory; distorted memory, false memory

Déjà vu (IPA: English , French ) (French for "already seen", also called paramnesia from the Greek word para (παρα) for parallel and mnēmē (μνήμη) for memory) is the experience of feeling that one has witnessed or experienced a new situation previously. The term was coined by a French psychic researcher, Émile Boirac (1851–1917) in his book L'Avenir des sciences psychiques (The Future of Psychic Sciences), which expanded upon an essay he wrote while an undergraduate. The experience of déjà vu is usually accompanied by a compelling sense of familiarity, and also a sense of "eeriness", "strangeness", or "weirdness". The "previous" experience is most frequently attributed to a dream, although in some cases there is a firm sense that the experience "genuinely happened" in the past. Déjà vu has been described as "remembering the future." See spirit explanation below.
