What does de ga vue mean?

"Déjà vu" is a French term that translates to "already seen." It refers to the phenomenon where a person feels a sense of familiarity or that they have experienced a situation before, even though it is happening for the first time. This sensation can be fleeting and is often accompanied by a feeling of strangeness or disorientation. The exact cause of déjà vu is still not fully understood, though it is often linked to memory processes.
