What French phrase meaning "already seen" describes the phenomenon where an event or experience seems eerily familiar?
assistant
Ah, the term you're referring to is "déjà vu." It's a French phrase that literally translates to "already seen," and it describes an uncanny sensation where one feels as though they've lived through the current situation before. Despite its eerie connotations, déjà vu is actually quite common and is thought to be a byproduct of how our brains process memories and perception. However, like many aspects of the human mind, it remains a fascinating enigma yet to be fully understood.
