Déjà vu
Psychological sensation / From Wikipedia, the free encyclopedia
Déjà vu (/ˌdeɪʒɑː ˈv(j)uː/ ⓘ[1][2] DAY-zhah-VOO, -VEW, French: [deʒa vy] ⓘ; "already seen") is the phenomenon of feeling as though one has lived through the present situation before.[3][4][5][6] It is an illusion of memory whereby—despite a strong sense of recollection—the time, place, and context of the "previous" experience are uncertain or impossible.[7][8] Approximately two-thirds of surveyed populations report experiencing déjà vu at least one time in their lives.[9][10] The phenomenon manifests occasionally as a symptom of seizure auras, and some researchers have associated chronic/frequent "pathological" déjà vu with neurological or psychiatric illness.[11][12][13] Experiencing déjà vu has been correlated with higher socioeconomic status, better educational attainment, and lower ages.[9][10][11][12] People who travel often, frequently watch films, or frequently remember their dreams are also more likely to experience déjà vu than others.[9][14]
