What if everything you experienced felt like you had already lived it before? Meet the people for whom déjà vu is every day.

It’s that moment when you mix up past and present, the real and the imagined, and you can no longer trust your senses. How is it that the world is the same but the experience is completely weird? It’s like tasting your own tongue. What is going on in the mechanics of your mind?

Welcome to Déjà Ville, a virtual world designed to induce déjà vu in order to understand what happens when memory and our senses, our past and our present, all get scrambled up together.

Deeply Human is a BBC World Service and American Public Media coproduction with iHeartMedia.
