Homonym: Deja (Vu)
Déjà vu is a French term that translates to "already seen." It describes the sensation of feeling that a current experience has happened before, even though it hasn't. This phenomenon can occur unexpectedly and is often accompanied by a sense of familiarity and strangeness.
Researchers believe that déjà vu may be linked to memory processes in the brain. Some theories suggest it arises from a temporary glitch in the brain's memory systems, causing a mismatch between the present experience and stored memories. While it is a common occurrence, the exact cause of déjà vu remains a topic of scientific investigation.
