How It Got Its Name🧐

The term “déjà vu” was coined in 1876 by Émile Boirac, a French philosopher and parapsychologist. Boirac introduced the concept in his book L'avenir des sciences psychiques (The Future of the Psychic Sciences), where he explored the mysteries of the mind and phenomena beyond the physical world.

“Déjà vu” is French for “already seen.” 

There are theories that scientists have proposed to explain déjà vu, but none of them are definitively proven.
