So our brain recognizes the similarities between our current experience and one in the past. These experiments have led scientists to suspect that déjà vu is a memory phenomenon. We encounter a situation that is similar to an actual memory but we can’t fully recall that memory. (For example, all of the bushes in a virtual garden were replaced with piles of trash to create a junkyard with the same layout.) One study found that participants reported experiencing déjà vu when moving through the virtual reality Sims video game when one scene was purposefully created to spatially map to another. Other scientists have attempted to bring on déjà vu using virtual reality. Then patients in the different groups were given a suggestion to either forget or remember the memory, which could later trigger the sense of déjà vu when they encountered the game or word. That memory was usually something simple like playing a game or looking at a printed word in a certain color.

In a 2006 study by Leeds Memory Group, researchers would first create a memory for patients under hypnosis. Scientists have tried to effectively recreate déjà vu in the lab. But scientists have tried using tricks like hypnosis and virtual reality. The very things that intrigue us about déjà vu are the same things that make it hard to study. We associate the feeling of déjà vu with mystery and even the paranormal because it is fleeting and usually unexpected.

That explanation is perfect for cyberpunk science fiction, but it doesn't give us any scientific understanding of the phenomenon. Spooky!Ĭarrie-Anne Moss, as Trinity in The Matrix trilogy, tells us (and Keanu Reeves as Neo) that déjà vu is a ' glitch in the Matrix'-the simulated reality that keeps humanity unaware that intelligent machines have actually taken over the world. Some think déjà vu is a sign that you're recalling an experience from a past life.

We call that sensation déjà vu, a French phrase that means 'already seen.' But what is déjà vu, and can science explain why it happens? Déjà vu feels like a 'glitch in the Matrix' Wait, have I been here before? Have we stood in this exact spot as you said these same words to me at some point in the past? Haven’t I seen this very cat pass by this very hallway already? Sometimes, as we experience a new event or place, we get that creepy feeling that it's not the first time.

Is there such a thing as deja vu theory
