What Is Déjà Vu?
Déjà vu is French for "already seen" — a phenomenon where, despite encountering a situation for the first time, a person feels an intense sense of familiarity as though they've experienced the exact same thing before. Most people experience it at least once in their lives, and it's reported more frequently among younger people in particular.
The Exact Cause Is Still Unknown
Because déjà vu is a fleeting phenomenon, it's extremely difficult to reproduce and observe in a lab setting. As a result, rather than one confirmed answer, it remains a fascinating mystery with several competing theories still being discussed.
Frequently Asked Questions
If I experience déjà vu often, is something wrong with my health?
Occasional déjà vu is a normal phenomenon, but if it occurs very frequently and intensely, it's worth consulting a neurologist.
Why do people experience déjà vu less as they age?
Multiple studies have reported that the frequency of déjà vu tends to decline with age, though the exact reason for this is not yet clearly understood.
