Why Does Déjà Vu Happen? | Smartest Year Ever (July 25, 2025)
Have you ever walked into a room and sworn you’ve been there before—even though you know you haven’t? That sudden jolt of familiarity is called déjà vu, and for centuries, it’s puzzled everyone from philosophers to neuroscientists.
In today’s episode of Smartest Year Ever, Gordy explores why déjà vu happens, how your memory systems glitch, and what modern neuroscience says about those strange moments that feel like reality on repeat. You’ll learn about false recognition, pattern saturation, and even why people with temporal lobe epilepsy might experience déjà vu more often.
There’s a scientific reason your brain sometimes thinks it’s stuck in a rerun—and it’s more fascinating than any paranormal theory.
Like, share, and follow if you’ve ever felt like this all happened before.
