Psychologists suggest that déjà vu may stem from memory glitches in the brain, where it mistakenly interprets a new experience as familiar. This can happen due to split-second misfires in processing or partial recall of similar past events.
Interestingly, déjà vu is sometimes linked to dreams. People often encounter déjà vu during moments that resemble past dreams, blurring the line between memory and imagination. This overlap may occur because our brains store dreams and real memories in a similar manner, enhancing the feeling of familiarity. While déjà vu is not predictive, it can provoke curiosity and reflection, leading individuals to wonder if their dreams foreshadow real events, thus adding an element of mystery to everyday life.
