Let’s talk about something crazy. Wait a minute, I actually talked about this! It seems familiar to me. Oh Come On! You feel like you already experienced this situation or been to specific place earlier even when you are visiting that place for the first time. That crazy feeling is called Déjà vu. Why do we experience Déjà vu?
Déjà Vu Eplained
Déjà vu is a French word which means Already Seen. It was named by Emile Boirac in 1876. Almost 70% of the humans experience Déjà vu at least once in their lifetime which we call Associative Déjà vu. But some people experience it too often because of temporal lobes epilepsy, a brain disorder which causes frequent seizures in brain which means sudden electric discharge in the brain which is called Biological Déjà vu. There are 3 types in Déjà vu, déjà vécu, already experienced; déjà visité, already visited; déjà senti, already thought.
Although the exact reason for Déjà vu is still unknown, there are tens of theories around it. Among all 3 theories are practically close to this sudden familiarity feeling.
When we are in a particular place or situation all our senses start receiving data synchronously and then send to brain for interpretation. If anything is not in sync, due to delay in data our brain processes it second time thus we feel we have already seen or experienced it. Actually we did but we can’t recall that memory thus we experience Déjà vu.
For everyplace or object we keep some pointers in our brain like identifying a place with a landmark. For example for years you are seeing a statue in your neighborhood. Next time when you visit a new place for the first time where you saw exactly same statue, you feel like you have been there before. Here for sure it’s your first visit but because of the statue that place look familiar to you making you feel Déjà vu.
We look at object or place for quite some time but we don’t do it consciously which means you are not paying attention to it. So our brain won’t register it. After sometime when we look at it again we feel like we have already seen it.
Experiencing Déjà vu once in a while is okay. But if you experience it frequently there could be some chemical imbalance in your brain. So I recommend you to consult a doc immediately. If you find this article helpful please subscribe to our infotainment YouTube channel for informative videos 🙂
