Why do I feel like Im always having deja vu even though I know the event has not happened before?

Feeling like you're experiencing déjà vu frequently can be linked to the brain's memory processing. It may occur when your brain recognizes a familiar situation but can't pinpoint where you've encountered it before, creating a sense of familiarity. Stress, fatigue, or even certain neurological conditions can also heighten these experiences. Overall, it's a fascinating phenomenon that reflects the complexities of memory and perception.
