Dejavu, I’ve come to realise on my own that they are simply a state of mind which are similar to that which we had felt before, and not that the event has occurred before. This could be triggered by similar events or themes that we observe, and anomaly of hormones concoctions released by our body.

The problem usually is we forget those exact moments that we are retrieving from memory, I have had a glimpse, or a notion of what they were, and they are not the same as what is happening at present, it only feels the same. Like a dream which we forget when we wake, only the feelings which remain.

The feeling of familiarity, without memory to equate it to, makes us think that what’s happening right now, may have already happen.

Your thoughts please.

Yes i also experience before sometimes in some places. I dont really know what this happens but maybe its just that situation being SIMILAR to something we've felt before and cant clearly remember. Hence we thought that we've experience this before.

or maybe that we've dreamt about something like this before. Then when faced with something near our mind thought its the same thing

Deja Vu is very abstract.
It's hard to describe in words.
It's the kind of feeling and expression you have when you felt like you've been through that moment before and you are repeating/reliving it.

Ya true.Its a feeling but it never happened before. Just a feeling it happened before

I guess everyone also experienced Deja vu before
yeah.... its very abstract, hard to describe I think its probably the things we dreamt, like there's so many dreams we've dreamt even though we don't really remember all of them.... and when we've come across something more or less similar in reality, we'll feel like it had happened before..
But that's just me hehe

True true. We dream everyday and 90% we cant remember the dreams. Maybe when we faced with the same situation in real life, then the memory of the dreams emerge and we kind have the feeling of been there

Yaya, exactly that Not easy to put into words

You feel like,
'hey, i've seen this scene before' and 'hey, i've dreamt about this before'.
but then again,
you don't remember yourself dreaming that stuff, but all you know is that everything is eerily the same.

ya ya true..btw why are we repeating the same things over and over again in this thread? Kinda un-phd like to me..

Hm. Yes...

Haven't i seen you say this before? In fact, haven't I MYSELF said this before?? It's...it's like...deja vu!

LOL, good one
I've seen cases on TV where a person has "forseen" the future... can't remember what it was, something about a plane crashing during a festival and he "predicted" that the pilot survived and he really did.... Wonder whether that has anything to do with deja vu or not
Or perhaps there's really such a thing as 6th sense?

Like most everyone else who posted here, I've gotten my deja vu experience mostly from the fact that I've dreamt something beforehand, then seeing it happen in real-life sometime after that.

My opinion is that there's definitely something more to our dreams than just unfulfilled wish fantasies, but the problem is separating the noise (dreams that will never happen) from the real deal. And until a dream really happens, we will never really know if it's "fake" or not.

So, I'd say it's a potential 6th sense. We just haven't really learned to use it well enough yet.

deja vu should not be mistaken as predicting future or premonition.

Cause with deja vu, you do not see it in advance. You will only realize it while the event is happening or after it happened.

http://www.cracked.com/article_17103_5-way...-your-head.html

yeah, i had my daily doses of reading in there.

From wikipedia:

Déjà vu (pronounced /ˈdeɪʒɑː ˈvuː/ ( listen) DAY-zhah VOO; French: [deʒa vy] ( listen), meaning "already seen", from Greek παρα "para," "near, against, contrary to" + μνήμη "mēmē," "memory"), is the experience of feeling sure that one has witnessed or experienced a new situation previously (an individual feels as though an event has already happened or has happened in the recent past), although the exact circumstances of the previous encounter are uncertain. The term was coined by a French psychic researcher, Émile Boirac (1851–1917) in his book L'Avenir des sciences psychiques ("The Future of Psychic Sciences"), which expanded upon an essay he wrote while an undergraduate. The experience of déjà vu is usually accompanied by a compelling sense of familiarity, and also a sense of "eeriness," "strangeness," "weirdness," or what Sigmund Freud calls "the uncanny." The "previous" experience is most frequently attributed to a dream, although in some cases there is a firm sense that the experience has genuinely happened in the past.[1]

What are you trying to say with that definition? Maybe you do not understand what I am trying to say. Okay here is my second attempt.


With deja vu...

The event happened, for example, an accident. You will only REALIZE that your have seen the images before WHILE it is happening or AFTER it has happened.


With premonition....

Before the event happen, you will yell...accident....you will KNOW the accident going to happen BEFORE it happened.


Both also deals with images or experience you had previously.

yea yea I have that experience too,
quite often sometimes.
and even you can recall that event, you just don't know what will happen next until it comes

Deja vu aside, when u mentioned dreams, i too think that dreams hold a hidden potential. Few yrs ago, there were things that i couldnt do, physically i mean like sports skill, then when once i dreamt of me being to do it in a sequence of dreams and few weeks later i was able to do it!!

Well said bro
With deja vu we won't know/feel that we've actually experience the event until we experienced it

I dunno about dreams but I've always believe the human brain holds hidden potentials

This post has been edited by [PF] T.J.: Sep 15 2010, 07:38 PM

Yeap. This is a much better definition.

i kinda feel like this is going to be your reply

Why...did you see it in a dream?

no its a feeling i experience u asking me this question b4

Ah, deja vu. What a nice feeling that is

I for one agrees that our bodies have lots of potentials yet to discover. However so, i noticed that, from personal experience, deja vu happens to me often when im in a tired state of mind. Could be that the mind is playing tricks on me.

i think that should be under hallucinating category already since u tired.

If I may explain my opinion here...

Deja-vu is something that going to happen or already happen in which our unconscious mind state has foreseen it.

It is a believe that human are living in mirrored type of world. where our unconscious mind are active which believe that has been experienced the same feeling in other world. Same as identical twins, when one feel sick another will be but Note that is not happen at that moment jus after few min, hours or even few days.
that's is the same concept which relates on the worm hole in universe.. there are many believe and theory based on this.

We have no idea that what act had happen in few million yrs ago in our earth. but we do conclude that the dinosaurs, pre-human and all these historical stuff based on evidence. But what if there was(or already had) a civilization in the world that almost similar like us who has experience the same event as we do now.

Remember that, human and all livings are a form of energy. Based on physics, Energy can not be destroyed or created but it changes the form. from this we have to realize that, the energy from million yrs ago still around but have changed form in way that adapt to situation.

So, Religiously people do believe in souls and these souls are around us . let say we assume that souls as energy as scientific term. What if these souls that we have in us are the same from the million yrs ago. So, that's why we might experience deja vu coz its already happened otherwise how we certain that its we had seen or feel before. I have discuss these concept to my physic lecturer and did some research also otherwise i wont crap here ...However its just a opinion only..

hope u can see the point in what i trying to explain here...

yeah i totally get ur point.
kinda right there.

but then again, when we experience deja vu, its usually regarding things that are current,
or how do i say, things that happen in everyday life,
not ancient things.
err do u get what i mean?

this is getting confusing.

yeah i get it.this is a good question how it relates to ancient.
U have to Note that Deja vu is something thats already happen that is why we experience the same feeling as we had before.

First:

okay, let say we go a place somehow we feel that we have been here but we can't recall it. but act it was our first time to be at the place.
hold on there...let us go backward million yrs ago..the same place was there either land or water.wat differ was how it had changed the place in aspect we seeing it now in term of building road and etc.But the atmosphere and energy around there was not changed at all..somehow we have been here.
So, wen it comes nowadays when we go a place which we feel deja vu and our mind state will form a memory based on the object or building around the place as if we have been here. This is for places or more on concrete object.

How bout feeling and thought that happen everyday?
have u experience that u have said this exact word or fact to someone before. these words been said before. there was another theory in this matter as well which is still in research . " when human are sleeping(deep sleep) where u dun aware what is happen around ur energy(soul) partial out of the host and it going all places with different energy form(energy that experience many event b4). Thats y we dream and things and word were said happen exactly as we have experienced before.

Second:

This is my own theory...How bout in trillion yrs ago there was a same identical world in same position of our earth where ppl like us had lived and this world had been destroyed due to universe cycle (something like BingBang Theory). somehow the energy is still there. thats y we might experienced deja vu.

Act, i have summarized in simple word for better understanding.

cool, i understand that.
that's quite logical.
and yeah, its the energies around us that makes us experience dejavu right?

and i've also heard a theory that dejavu is related to reincarnation or some sort (in some beliefs).

glad u have understand it.
Reincarnation mite be related...i not really sure at this part..maybe further studies will clarify it..
Cheers bro..

Deja vu is a memory of a future event. One that hasn't occurred yet. If you're wondering how we can remember something that has yet to happen, the explanation is simple. There is no free will. It is just an illusion. We are characters in a movie. We think that we are making choices, but in fact everything has already been laid out. The future is predetermined.

wow..i have a deja vu now....wait..no...it's a context from the movie Matrix...

hehehe... I really donno what to comment, this thread has taken a life of it's own.

That was in the Matrix ?? Strange. I don't remember that. But I've only watched the first one. Don't remember it ended like that. Maybe it was in part 2 or 3, and that was my memory of what I will see when I watch them in the future?

Actual observational proof of the hypothesis.

sounds creepy that what we are feeling now is the result of predestined and just acting it out, I wonder who is watching? Also, in cases of rape & kill, the girl should just let it happen if it unlucky since its their destiny. I do accept that we may be led to do what we did but the result is not entirely made, the more you believe the less likely you will achieve anything in your life because you accept the life as it is and be an ordinary person subject to influence such as terrorism act.

Deja vu only happens after you've experienced it right at that moment rather than things that will happen in the future and it could be tied with some dreams we have had before, if you have seen movies that had glitches during playback, you too will notice something like Deja vu. The nearest answer is our brain had suffered such glitches and when resume, it playback what we were doing at that moment.

Even so, I do feel that there is a chance we might be the puppet in a show and that is why people who nearly die and came back to tell bizarre stories. How do we come up with god in the first place, also heaven and hell? If its there, we are not supposed to know and if you are afraid, you better behave if after death is what you live for.

My thoughts on Deja vu are very similar to firedemon's in relation to energy recycling and the Big Bang theory. I think we are working on the same theory but will explain what i mean in case it has some differences.

I saw a documentary once in which a scientist (i don't remember the exact field nor can i take a guess at what field would specialize in water, chemistry perhaps?) found some evidence that water retained a form of memory/information. If this is true and even water can retain memory then perhaps energy itself is able to retain memories as well.

Then if we add in the theory of the Big Bang (and equally importantly in this case the Big Crunch, where at some point in time the universe will stop expanding and collapse back in on itself) it would suggest that it is possible that there could have been many rounds of Bangs and Crunches leading to the universe being formed and destroyed many times.

Take on top of this a similar theory to Parallel universes/ A Multiverse, but instead of each universe existing at the same time, they follow one after another (i'm not sure if there is already a theory covering this idea, i would assume so although i couldn't find it).

Putting all this together it would be possible to theorize that our feeling of Deja vu is actually a memory stored in the energy we are made of which has been in a similar (if not exact) situation before.

The main flaw in this theory, from what i can see, would be the unlikelihood that energy and particles line themselves up in almost the exact same way with each Bang/Crunch cycle to create a world/universe similar enough to our own that identical (or very similar) events could occur to create Deja vu, especially when you consider that the only reason our universe was formed was due to the random arrangement of matter after the Big Bang allowing gravity to work to eventually form stars, planets and even us.
But then if you followed the theory that time and space are infinite, it would be possible that an infinite number of Bang/Crunch cycles had already occurred meaning that every possible scenario was played out, in which case why is our whole life not one constant string of Deja vu?

The spanner-in-the-works here is the expansion of the universe is accelerating rather than being slowed down by gravity. So there would likely be no big crunch. Hell will freeze over though. Or at least the universe does.

http://en.wikipedia.org/wiki/Big_Freeze

Oh, of course. I forgot about that nasty little theory. Sadly the Big Freeze does seem to be more probable than the Big Crunch these days. But i still hold out hope that we are in an endless cycle of Bangs and Crunches, not to keen on the idea that we are destined to end up constantly drifting further and further away from the rest of the universe.

Otherwise perhaps Deja vu is simply energy remembering from a previous human it occupied who experienced something similar? Although there would have to be something in a theory like that explaining how our brain interprets the memory to fit our life (the actual memory was of seeing 2 horse carts but our brain translates it to cars, stuff like that).

i agreed with your thoughts and it is brilliant thats you have taken in account of the universe and space theory.

Hum... Are you guys familiar with Occam's Razor?

I think it's more likely that it came from something we experienced, but our brain messed up what it means.

I've read this book regarding our mind from readers digest. It explains why we have altered feelings. Are our days always the same? Or are some days for no apparent reason, brighter or gloomier than others?

We think, we feel, we remember; all these comes from our brain. If it is tempered with, either from physical damage, surgery, or mind altering drugs, I can tell you that everything will change for you.

As perfect as the human body is, there are still defects that we are born with from moles on our body to brain aneurysms.

It is no surprise that we may wake up one day, to feel that everything in this world is so wonderful.

Likewise, I guess it's normal that there are moments in time, that we are struck with a "hey that feels familar" state of mind.

The triggering mechanism probably misfired on having seen something which is similar.

For example, if I tell you: Salmon, Octopus, Seaweed. You'd group them as the theme, "under the sea".

The next time, if you are told: Tuna, Squid, turtle, submarine. You'd group them as the theme "under the sea" as well, making you ask "hey, have I done this before?".

If I ask you whether I've mentioned them before, you'd say no... but you've got this strange feeling like I've mentioned it before.

These existing memories can come from dreams or real life. I understand and agree that when we sleep we may be constantly dreaming, just that we do not know that we are. But I think that there is no significance, that the memories must come from dreams.

As for the other theories, I don't think we need to go that far, do you?

Added on September 20, 2010, 4:04 pmAs for water storing memory, I'm afraid that will need proper references because it's a little far fetched.
Could it be that what they meant was to retrieve bacteria samples from stagnant water, or ice, to tell where it has been?

Energy (EDIT:) cannot be created or destroyed . Yes

Energy stores memory?
Memory can be retrieved when energy that has been together meet?
Energy remains at one place?

How much memory can a single unit of energy store? everything that it has been through?

Do we need a collection of energy to paint the picture? In which case it must all come into place before the memory is triggered?

Deja-vu par excellence

Xuzen

Groundhog day movie is the person keep repeating the day not a Deja-vu which is split second as if feelings.

sometime u feel like the thing u doing now include the surrounding, environment, ppl that u hv done before

Haha... I just had dejavu today. I can't explain why.

I felt like I had been in the meeting before, and the same issues were raised. In the imagined meeting, I said "Eh, I felt like this happened before", and people asked me what I meant. In the actual meeting, I just stared blankly at the speaker.

Could have concocted the scenario in the dream before and pop up as it happen, fragments of dreams do kept in memory. The similarity could be close but not necessary exactly apart from the brain laps.

I read one explanation of deja vu long time ago. The brain is divided in two halves. It's just that one half of the brain already experienced the reality whereas the other hard is a bit "slow". So when the slower half catches up, it seems like you experience something that has happened before.

Hope I'm making sense.

Yeah know what you mean. That's interesting.

Experienced something like situation which I believe had occurred before but in nowhere.

personally thought it's something that regularly done but overwritten with something similar. nice thread though. I think I've found the answer from here.

Means like we have another half of the brain already experienced the future while the other half is slower and still in the past/present?

Dejavu happen when a microvortex appear in a space time continuum and it happen in the proximity of someone's brain when they sleep. It's not powerfull enough to carry physical entity, and it's not powerfull enough to carry your brainwave when you're awake and in full control, but when you're in an alpha state, your control over your brainwave is weaken and this were suck in and transfered randomly through time and space. Sometimes it goes to the past where you can't differentiate it from your pass memory. But sometimes it goes into the future and this memory from the future where stored in your subconcious mind. When reach the specific time and place, it triggered your subconcious memory and you feel that you've been here and done this before.

No, this theory has nothing to do with future/past/present.

A external event happens, black cat walks past door (in first Matrix film). The right brain receives the input and registers it. Left brain receives input split second slower. Anyway both sides are connected, and as a result you get the feeling you saw that cat walk past before. Clearer?

i always experience deja vu. any significance?

I think you might have brain damage.

I don't think its possible even though I really like the idea as shown in Assasin's Creed

Jamais vu - the opposite of deja vu, try writing your name repeatedly for, say 80 times..and then pause awhile.

http://en.wikipedia.org/wiki/Jamais_vu

In school, teacher punish us to write "I am sorry, I promise to behave" 100 times but does not seems to have any effect? Just hand sore.

Deja Vu is not as scary as Jamais Vu.

I get de ja vu sometimes, and the feeling is nearly inexplicable - it's vague but oddly familiar, like you have "been there" or "heard that" or "seen this" before, but you're not sure when or how or where, like a badly remembered dream, or semi-conscious day dream. It's bizarre, and sometimes unsettling.

I would love for science to be able to explain this. Is it memory-linked, or is it random subliminal brain activity?
