TIL: Nobody Really Knows What Déjà vu is...

Today I learned...


Most of us had the that experience.., where we feel like -- "we've been here before," or -- "haven't we met..?" You are positive, you can feel it in your bones.

But what is it..? What is actually happening that gives us "that" feeling?

It's usually accompanied by a strange sort of feeling… But as usual, us humans have to explain everything. "There must be a logical reason for this…" And there are -- there are actually a few different "logical" reasons for it.., which leads me to believe -- they have no idea why this happens and are just trying to squeeze it into a box, in an effort to understand, everything.

1. One theory is there is a split-second delay in transferring information from one side of the brain to the other. One side of the brain would then get the information twice – once directly, and once from the 'in charge' side. So the person would sense that the event had happened before.

2. Another theory is "cryptomnesia", which is where information learned is forgotten but nevertheless stored in the brain, and similar occurrences invoke the contained knowledge, leading to a feeling of familiarity because the event or experience being experienced has already been experienced in the past.

3. And another one is… Certain drugs increase the chances of déjà vu occurring in the user, resulting in a strong sensation that an event or experience currently being experienced has already been experienced in the past. Some pharmaceutical drugs, when taken together, have also been implicated in the cause of déjà vu.

4. Another… some researchers to speculate that the experience of déjà vu is possibly a neurological anomaly related to improper electrical discharge in the brain, creating a strong sensation that an event or experience currently being experienced has already been experienced in the past.

5. And some link it to… good memory (c'mon, really…)

6. Here's another one… the feeling of having previously seen or experienced something that is currently being seen or experienced to that of having dreamt about a similar situation or place and then forgetting about it until one seems to be mysteriously reminded of the situation or the place while awake.
   
   

And Im Sure There Are More…

What's wrong with taking it at face value…

YES.., you have been here before

We did meet, before

I have done this already

All in another lifetime!

But that would have all kinds of implications, that most scholars or scientist are just not willing to buy. Why can't they be actual memories seeping into our present life… Or a message from your higher self.., a glimpse into your soul.

I guess it is up to each us to believe what we want when it comes to Déjà vu. I myself, don't need to explain everything.., and would like to think it is the cosmos itself dying to communicate a message -- important or not. Just letting us know -- "You've been here before and that's okay."

BTW Déjà vu literally means -- "already seen."
And there is déjà vécu means -- "already experienced."
And also déjà senti means -- "already thought."
And another déjà visité means -- "already visited."
