Déjà Vu

Déjà vu is a French expression meaning "already seen," coined by French parapsychologist ÉmileBoirac in 1876 to describe an inexplicable – and often unsettling – sensation of familiarity while experiencing something for the first time. Although déjà vu has become a blanket term for any experience of this feeling, it technically only applies to visual information. Later researchers further divided this sensation into déjà visite ("already visited"), déjà vecu ("already lived through"), déjà senit (“already felt”), and déjà entendu ("already heard").
