Why do we have Deja Vu moments?

Question

As a 10 year old I remember visiting the Isle of Man for the first time on holiday with my parents. While walking in the capital of Douglas I rmember turning a street corner into a large open square and at that moment I knew I had been here before.

Answer 1

what happened to you is known as DEJA VISITE

something like this happened to me when i was a little girl, me and my parents visited this old castle in India and I had never been there before but i knew my way around and i felt like i was having flashbacks. i had also dreamt of certain areas in the castle .... I was disturbed by that for ages and slowly learnt to accept that it is just one of those things nature
that no one can explain.
I often get deja vu moments when talking to friends like I have heard this before, felt this before, seen this before

the best explanation i can come up with is reincarnation. having visited this place in a previous life. nothing else explains it (to me anyway)

i found below explanation from wikipedia.org

Déjà visité
This experience is less common and involves an uncanny knowledge of a new place. The translation is "already visited." Here one may know his or her way around in a new town or landscape while at the same time knowing that this should not be possible.

Dreams, reincarnation and also out-of-body travel have been invoked to explain this phenomenon. Additionally, some suggest that reading a detailed account of a place can result in this feeling when the locale is later visited. Two famous examples of such a situation were described by Nathaniel Hawthorne in his book Our Old Home[6] and Sir Walter Scott in Guy Mannering.[7] Hawthorne recognized the ruins of a castle in England and later was able to trace the sensation to a piece written about the castle by Alexander Pope nearly a century earlier.

C. G. Jung published an account of déjà visité in his 1952 paper On synchronicity.[8]

In order to distinguish déjà visité from déjà vécu, it is important to identify the source of the feeling. Déjà vécu is in reference to the temporal occurrences and processes, while déjà visité has more to do with geography and spatial relations.

Answer 2

Neural network anomaly.

The experience of Deja Vu is nothing more than the same sensory input traveling through the brain twice, through routes of (very slightly) different lengths. This probably happens a lot without it being noticed, and the brain records only one of identical but multiple memories.

When you are having that Deja Vu moment, the difference is significant enough that you consciously notice it prior to the brain discarding the duplicate input.

Answer 3

Because time is not a straight line. It is a direction, like North or South or Up or Down. And while we generally follow our consciousness on a straight path through this field of space we call time, it is not inconceivable that our minds might hop around a little.

Perhaps you really did experience that moment before, two seconds ago, and your mind skipped back along this 'line you're carving' through time, picking up where you were a few seconds ago, but with no prior knowledge that are about to live the next moment for the second time.

Your mind may indeed, on some level, recall having been through the experience twice, but as you have no evidence to back up being there before, and wouldn't be able to express a quick 'skip in time' in terms you're familiar with (since usually you're cruising along on a straight line), then we feel a sense of Deja Vu.

metaphor later added for clarity: Think of your life as the spiralling path on an old LP record, the needle tracking on the record your path through life. Your life, your existence as you know it, is the song that is being played. Now imagine that record were to skip backwards at some point, and reply a couple seconds of music, and then continue on playing forward. Reality, the song as it's recorded on the album, is not altered in any way. But your perception of it as your mind rides on the end of the needle, would sense a repeat that it wouldn't be able to account for.

I'm no physicist, or neuroscientist. These are just my observations from my various readings.

Answer 4

The most logical hypothesis is this.
You take some memory from your brain and then you mix with another memory in an another part of your brain. This will will make a whole new story or "memory" in this case. And then it will become "deja vu"

In your case, you "rmember turning a street corner" because you have been turning in a lot of street corners in your life! And then you saw a "large open square". This may come from one of the mathematical problems you have done for your General Exam. *chuckles*

For more unproven hypotheses go to... wikipedia and search deja vu. An interesting read tho.

Answer 5

Human being has Mind and Memory, in memory there are lot information and images stored.
While thinking or speaking you can use either the Mind or Memory part,
If you use the Memory part you can easily have a Déjà vu Moment because you are using already stored information and images.
Women usually use Memory part while speaking or thinking .

Answer 6

People have real problems and genuine change they want make, your issue is genuine and this is way you need a real option. You need to seem like you in fact have a method to start making the modifications in your life. This is where this guide Manifestation Miracle that you can discover here https://tr.im/KEgP3 excels due to the fact that, if your life isn't the life that you desire, isn't ideal YOU CAN do something making it your method.
In this guide you aren't taught anything wonderful about Manifestation. Rather you're taught the ways you require to believe in order to alter the environment around you. When you alter your environment, you have the ability to change your conditions. Altering your conditions means changing your conditions. When you alter your condition you alter your thoughts and this is turn will cause different habits on your part. This different behavior is going to help you to cause all sorts of modification that will draw specific things to you like never ever before.

Answer 7

Why would you freak out? I like when I experience déjà vu. Anyways, don't worry it's normal it wouldn't hurt you at all.

Answer 8

this is quite interesting, especially the answer by April Girly. I also have these moments and sometimes I believe that this is because of reincarnation or something we have visited from our past lives... Although there is not a scientific explanation for this, I too had experienced such. When I was 13 back in 1990, I went to the place where they had the Woodstock event in 1969. I know that it is in Bethel, NY. Anyway, I had this weird feeling of familiarity of the place, like I felt like I had been there. And for some weird reason, I enjoyed everything about the hippie days and even my older brothers commented how I know a particular soong from the 70s by heart although I wasnt even born yet when that song was released. :) I felt like I lived in the hippe days and was one of them. :)
so really, I think there must be some unexplained reason for this

Answer 9

I saw a report in which it was said that this is because a delay in our brain. This "I have been there" results of the time gap.

I prefer to think that it means our mind may travel without our body.
