What is dayavu?

Answer 1

Dayavu, often spelled as "deja vu," is a psychological phenomenon where an individual feels an uncanny sense of familiarity with a situation or experience that is actually new. It typically occurs unexpectedly and can leave a person feeling puzzled, as if they have lived through the moment before. Researchers suggest it may be linked to memory processing or cognitive glitches in the brain. While generally harmless, it can provoke curiosity about the nature of memory and perception.
