Déjà vu (/deɪʒɑː v(j)uː/ DAY-jah-VOO, -⁠VEW, French: [deʒa vy] ; "already seen") is the phenomenon of feeling like one has lived through the present situation in the past. 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. Approximately two-thirds of surveyed populations report experiencing déjà vu at least one time in their lives. The phenomenon manifests occasionally as a symptom of seizure auras, and some researchers have associated chronic or frequent "pathological" déjà vu with neurological or psychiatric illness. Experiencing déjà vu has been correlated with higher socioeconomic status, better educational attainment, and lower ages. People who travel often, frequently watch films, or frequently remember their dreams are also more likely to report experiencing déjà vu than others.
