Everyone is familiar with Deja Vu and how uncanny it is to experience one. We all feel it now and then. If you’re not sure and are lazy enough not to google the phrase, I’ll tell you about Deja Vu in a straightforward statement. Deja Vu ( or déjà vu) is something that someone believes they have seen/heard before, which is generally not the case.

Consider yourself bag-packing to somewhere in India where you’ve never been. You’re excited, a new place awaiting your arrival, and Bam! A weird sense of feeling of being in that place before. Drinking the same root beer from the same barkeeper as before, having a laugh on a joke you think you’ve heard/made, but you know that is not true. This uncanny feeling is Deja Vu.

Many theories are explaining the reason and cause of this event. Many are stating this as a gift from God to change the future willingly by re-experiencing an event. Some noted that this is just normal behavior of brain when sometimes it is high (drugs or not) or just over functioning. And some of the others said this is just brain catching un-received signals from other brain sent some time ago. (If you’re feeling funny on the last one, let me tell you one thing, it is true[1], but that’s not déjà vu. I’ll get to that later).

Scientists even have thrown this in the garbage in earlier days, stating this Deja vu stuff – ain’t real. Until a few months earlier, when a team of scientists actually solved the Deja Vu mystery.

When the brain tries to correlate the events or people, places, and things nearby to similar memory from the past, it forms an image of you doing that thing as if you have already done.

Understanding Deja Vu

To understand this better I’ll tell you an example. Ever heard of YouTube buffer? Or storage cache?

YouTube pre-downloads a video when you’re watching it online. To give you the best experience and thank god, YouTube offline made its way to India because it sucked. Getting to the point, YouTube stores a little later part of your video so that you can watch it flawlessly(apparently), and that’s what our brain does. It predicts the near future unconsciously and gives you a deja-vu-sensation. —- (1)

Similarly, consider your computer, which has some cache storage built-in. “Cache” simply stores the most or recent visited memory locations of your hard-drives so that you can get access to them faster. Gosh, I managed to make it sound so geeky. Our brain is marvelous, and it fetches the history stored somewhere in it to link it to the present to save you from confusion or a sudden feeling of overwhelm.

Wow, and it does that with déjà vu (Irony).

But this theory is not my favorite. I still like to wonder if I’ve done that in a past life. Ooh, Spooky.

Conclusion

A few years earlier, I attended some mind-peace sessions. Well, they were free of cost, so who is to judge. They used to teach stuff like meditation and karma, which is for me, a half glass full.

According to them, the universe is a 5 Millennium cycle. God is playing a CD continuously (It’s not my metaphor). And it means everything that is about to happen has already happened. If you’re reading this right now, you were reading this 5000 years ago.

So, this theory basically fails many scientific achievements so far, including carbon dating. So that means the bristlecone pine tree is not real. No matter how fallible this theory actually is, it holds some ground, to say the least. When Pythagoras said the earth is round, we all remember how the great scientific minds treated him. Or Phileas Fogg, who actually traveled the globe in 80 days, I’d like to keep my mind open.

Note: Around the world in eighty days is a fictional novel. But it is a classic. And quite possible.

Remarks:

[1] Like many myths of reality, brain-wave is actually getting a little scientific attention. And more research would find the reason why someone nearby starts humming the song you were thinking just a second earlier. I’d post more on this later.
