Why Do We Get Déjà Vu? | Brain Glitch or Memory Science

Have you ever felt like you’ve experienced a moment before — even though you know it’s your first time? That’s déjà vu, a curious phenomenon that fascinates both scientists and psychologists.

🔁 Memory Recognition Misfire

Déjà vu may occur when your brain's memory system mistakenly identifies a new moment as familiar. It’s like your brain sends a false “memory signal” even though no actual memory is present.

🧩 Dual Processing Theory

According to this theory, your brain processes the same information twice — but with a slight delay. The second processing feels like a memory, creating the illusion that you’ve been here before.

🧬 Implicit Memory Activation

Sometimes, déjà vu is triggered by a detail that reminds you of something you've experienced before — a smell, a color, or a layout — even if you don’t consciously remember it.

🧠 Brain Health and Déjà Vu

Occasional déjà vu is completely normal, but frequent episodes could be linked to neurological conditions such as temporal lobe epilepsy. If it happens a lot, it’s worth checking with a doctor.

Conclusion: Déjà vu is your brain's way of processing and recognizing patterns. It’s a fascinating reminder of how powerful — and mysterious — our memory systems can be.
