Déjà vu

Recall the last time when this happened; you are sitting in a room chatting with someone or just doing something and all of a sudden there is a flash in your brain and you say to yourself , ‘hey wait a min I was here before doing exactly the same thing ’ or ‘I had the same exact conversation before’. But you cannot remember when did this happen before. You think there is no way I could have lived this moment before! ‘But it feels like I have!’ Then you remember you had a dream about living this moment before. ‘How could I have a dream of living this moment exactly as it is before it really happened? Wow! Déjà vu!’
It is amazing enough to know how our brain interpolates data, perceives things, feels emotions, dreams and synchronizes with organs. Irrespective of all those, Déjà vu, for me, tops the chart for the most amazing thing that the brain does. Scientists although baffled at how this happens theorize that it’s an anomaly of memory. But the fact that events stored into memory before the conscious part of the brain even receives the information and processes it1 is simply hard to digest.
Consider déjà vu may be a form of familiarity-based recognition1 (recognition that is based on a feeling of familiarity with a situation). For a feeling of familiarity to exist there should be a situation that has happened to compare with the current one. Is it possible that sometimes the brain fails to comprehend a particular situation as a fresh situation and falsely signals to indicate that the situation has actually occurred before? If this is true, here is a thought to ponder on. Consider if you can have a déjà vu deliberately. Now when you are learning something new you have a déjà vu. The brain says to you that I have already learnt this before but actually you are learning it for the first time. The brain will have a strong memory of have learnt this next time in the future. Won’t this make easier for kids to learn difficult quickly?
The extent and frequency of déjà vu a person can have varies from person to person. Since it’s a fact people do have déjà vu, it’s not hard to believe some people may have more of it and some less. But we almost always bother less about this amazing phenomenon. A self analysis of what kinds of déjà vu you have can go a long way in getting to know yourself better. You may not solve the mysteries of the brain by doing so but you may get closer to knowing the most mysterious you better.
