Definition Of Deja Vu

A man drives into a city for the first time in his life, and for some reason it feels familiar. He knows he has never been to this city before and it shouldn’t have felt familiar, but it does. This man is experiencing the well known phenomenon of deja vu. Already seen may seem like the definition of déjà vu, but it’s the literal english translation of the French word. A more specific definition of déjà vu could be a feeling of familiarity with an unexplained origin, but déjà vu isn’t nearly this simple, in fact scientists still aren’t entirely in agreeance on how the process works. This uncertainty amongst scientists and researchers can be credited to the unpredictable nature of déjà vu, but the general consensus on déjà vu is it’s is a scientific process in your brain where one section thinks something happened and another knows something couldn’t have happened.

One such theory bases its claim off the multiverse theory. According to Michio Kaku alternate universes exist all around us, but we aren’t able to access them. This is due to our universe’s atoms vibrating at a certain frequency that other universes are not, except sometimes. Sometimes our universes atoms can be vibrating at the same frequency as another's atoms making the 2 universes in phase and when the universes are in phase we can move back and forth between universes without realizing it. This vibration at the same frequency could cause deja vu meaning that deja vu is a window into other universes (Can Parallel Universes Explain The Déjà Vu Phenomenon?). Except this isn’t the case. Deja vu can be explained through science and study of brain function and isn’t a window into another universe like the mentioned theory
