40 Strange Photos That Make You Do a Double Take

You know that feeling you get when you’re like, “I’ve been here before,” but you haven’t? Yeah, that’s deja vu. According to science, deja vu happens when your brain processes information to make it feel familiar, even if you haven’t experienced it before. It’s like a glitch in the matrix. 

But don’t worry. Deja vu is completely normal, and most people experience it eventually. Some studies suggest that people who experience deja vu more often may have a better memory. So, next time you experience deja vu, think your brain is working extra hard to ensure you don’t forget.
