What is DEJA VU really

"already seen"
they're small seizures that trigger memories or things you have seen in your life

It is a feeling that you get when you do something or see something that you think you have seen before or maybe imagined that you have.

In my opinion, Deja Vu starts out as something you have dreamt about and then subconcioussly, when you are in the location or are around the people you dreamt about, you do something that initiates this same thing that happened in your dream. That's just my opinion on it.

Its when something happens & it feels like you've already done this or its happened before .

For example, say you go to the mall & see this awesome shirt . But somehow , it looks familiar even though you've never seen it . That's deja vu . It means literally , already seen .

Deja Vu literally means "Seen Already or Already Seen". It is the feeling one gets when they feel like they have either seen or experienced the current situation. I believe the term was invented by Émile Boirac who was a French psychic researcher.

French: Deja Already; Vu past tense form if to see Already seen. Usually its when you have a dream about a place or a conversation then actually experience that event.

Neuro scientists believe that from timt to time, certain brain functions experience a "lag". As they speed up to catch up with the rest of your cognitive processes, you experience deja vu.

True Deja Vu is when the exact same things happen. It is not just a feeling or a co-inscidence.

I think I've seen this question before somewhere.

It is a feeling that what has just happened has occurred to you in exactly the same way at sometime in the past.
