Why Déjà Vu Feels Like You’ve Lived This Moment Before

You walk into a room you’ve never seen before. Everything is new. But suddenly, your brain tells you this exact moment has already happened. That strange feeling is called déjà vu. For centuries, people have explained it with past lives, dreams, parallel universes, prophecy, and glitches in reality. But the real explanation may be even stranger. In this video, we explain what déjà vu actually is, why your brain can make a new moment feel old, and how a tiny mistake in your memory system can make reality feel like it repeated itself. #dejavu #brainfacts #weirdscience #psychologyfacts #cartoonexplainer
