Deja Vu.

People when experience something , sometimes feel that that situation was familiar to them either through a dream or a random thought . I too have experienced it multiple times .

Sometimes it"s related to situation involving people around you . There can be a reason for this. Because we tend to think of people related to us. Random thoughts etc.

But what about random people . Strangers . With whom we don"t have any connection.

So what I feel is ( I also have read it somewhere , so just linking it) , this Déjà vuis related to the concept for Multiverse.

What is déjà vu and what causes it?

(Image : Multiverse concept was applied in DC comics too)

Multiverse refers to the concept of infinity number of universes that function simultaneously . Most of the functioning will be the same except for a change in few incidents . Example : In this universe my name is Vamsi , in another universe my parents would have kept Madhav as my name. Or a major change like be joining BiPC after 10th instead of MPC which will cause a ripple in the time frame causing major changes in other"s lives related to us.

Now what I believe is that though there are infinity number of universes , there tends to be connection /sync between minds of same person of different universes.

So sometimes we feel as though we have already experienced an event previously. This is possible because in that in another universe we might be already Experienced that event .

I recently come across an incident which was written in quora .

A lady experienced a dream in which the she and her hubby were in a room where they see a girl moaning . The hubby starts to run towards the girl to give her some water. The lady asks her hubby not to leave her. “ Dnt leave me alone” she says and at that point she wakes up .

Later with a disturbed mind she goes out in the morning in the building coridoor . Suddenly she hears a “thud” noise .

A girl committed suicide by jumping from the roof. Then her hubby starts to run down with bottle of water . The lady requests him .

“ Dnt leave me alone”

My reasoning is this .

In the first situation .. the dream is due to a similar situation that has taken place in an alternate universe but in that Universe the girl didn"t die on the spot . So she was moaning in paining (alternate universe). The same thing was in her dream due to the sync between the minds of people in multiple universes.

Who knows … dreams or nightmares might be a result of multiverse.

In a nightmare you might have got the dream of you dying . That could have happened in another universe.

Random thoughts , day dreaming everything might be associated .

Maybe everything is interlinked.

Multiverse may be the reason for Deja vu .

But wait

Deja vu might be the proof that multiverse exists .

.

This is my reasoning .

Maybe I am thinking too much .

But doesn"t me I am wrong . ��

Réponse d'origine: How does deja vu happen?

Deja vu is a source misattribution error where you experience your perception as a memory. This has been demonstrated experimentally through false alarms, where a person misattributes a new item as one that has been already learned. An example would be seeing several paintings by Leonardo Da Vinci and then being shown a new one but thinking you had already seen that painting. Short term memory has a hard time discriminating items that are similar in sensory perception. Long term memory has difficulty discriminating items that are similar in meaning. This occurs because the same neurological areas in the brain are used for both perception and memory.

Deja vu is when a perceptual experience stirs up a similar but not identical experience you have had before. There are also brain disorders which lead to persistence deja vu, this occurs due to a high number of false positives in source attribution.

Basically your criteria for discriminating memories from perceptions is too low. Everyone establishes a threshold of familiarity where once you pass such a threshold, you experience the sensation of a familiar experience. This threshold is part of the signal detection theory. Basically when you have a perceptual experience your neurons start firing on pathways. When the signal has a high familiarity you have a feeling of knowing it, whereas with a low familiarity you dont. Where you set this threshold determines how often you “feel” deja vu without having actually experienced it in the past before. The optimal threshold is neither very liberal nor very conservative but right in the middle to balance false alarms (thinking an item was seen before when it was not) and misses where you studied it before but failed to recognize it. Those who persistently experience deja vu have this threshold too low, and any similarity of current reality to a past experience triggers a feeling of familiarity.

This may be due to a disruption of the fronto-temporal circuit. However it is theorized that there are actually two forms of deja vu, one is for recollection and the other is for familiarity.

Memory is a reconstructive act, it is not a retrieval experience that most people think it is. When you remember or experience deja vu, your brain is actually recreating an experience it is not recalling an actual one. Due to the fact that your brain recreates memories you can experience memory distortion leading to feelings of deja vu which are not real.

For healthy individuals, most deja vu is the experience of familiarity without being able to recall the details of the event. This is because familiarity and recall are two separate memory processes. In brain damaged patients who are unable to recall memories, they can still experience familiarity.

Réponse d'origine: What causes déja vu?

Deja Vu usually stems from the fact that during your dream state, your consciousness attempts to solve your life problems by co-creativity working with the consciousness of all other beings in order to arrange your life into a series of synchronistic events. These events are meant to provoke your conscious rational into a path of greater realizations that will ultimately allow you to solve all of your own problems and realize your true potential.

The challenge of experiencing this for yourself is that your consciousness makes use of all the desirable and undesirable experiences that could possibly occur. When life happens and difficult experiences are thrust upon you, you may mistakenly assume the worst, as if those events happen solely because of poor choices or bad luck. A more correct approach is to assume these events will support you in the greater vision of life that you have yet to discover, and to diligently keep an open mind, so that you can utilize the next synchronicity with greater clarity and equanimity.

The Deja Vu experience is a residual effect of your consciousness projecting itself into the future during your dreamstate and the impression being so significant that when you have chosen to walk down that path in real life, you suddenly remember that moment as if you have been there before. You have.

Why don’t you remember this cause more clearly?

Upon awakening from the dream state, your sub-conscious awareness attempts to consolidate the vast amounts of information into a symbolic representation that your identity can make sense of consciously. However, these symbolic consolidations can remain far from the true portrayal of the actual events they are meant to convey, depending on the individual’s belief system. These dreamstate projections are what we call dreams upon awakening, which are designed to imply a vast wealth of information in a simplified format. Unless you have previous training in remembering these dreams, or have experience in becoming consciously aware during them(lucid dreaming), you may never make this connection to your Deja Vu experiences. I have.

More vivid experiences of Deja Vu could be considered Precognition or seeing the future.

Alternatively, you can die and choose to reincarnate from the beginning of your life or at any point in transition, even resuming from the point of death while not knowing you have died, and have Deja Vu from reencountering pivotal life choices. My childhood friend has a personal experience of this occuring for him as a child.

All of this may appear as theory, unless you choose to develope the skills of concentration and direct your awareness deep enough into the investigation your Self, or the interconnectedness of all information from all disciplines of experience.

If that is your interest, I invite you for some further reading:

Réponse d'origine: What is déjà vu and why does it happen?

Déjà vu (French for “already seen”) is an experience that many people have (roughly 67% of the adult population say they have had such experiences) in which they have the startling impression that reliving an event or revisiting a place while at the same time knowing this is not possible. These experiences are usually stunning, even baffling. They generally last for a very short time (but there are exceptions) and vary in intensity. People tend to have them when they are young and they become less intense and less frequent as they get older. For some odd reason, they seldom occur during situations or places that are in some way important or momentous. They sometime involve precognitive knowledge in which the person having the experience knows that will happen before it does or they know what is around the corner or in the house before going there. Often, such uncanny knowledge is attributed to dreams that were not remembered until the moment when they are suddenly “coming true”.

Over the years, many hypotheses have been put forward to explain why and how these uncanny experiences happen. I am convinced there are various forms of “déjà experience” and each type may have its own explanation or cause. If you wish to know more, I highly recommend a 2004 book by Prof. Alan S. Brown called “the déjà vu experience” or go here: Welcome to the Déjà Experience Research Website.

Réponse d'origine: What is the explanation for experiencing "deja vu"?

Hi Deja Vu is something which we all have experienced at least once , in my case its more than once .
Lets see what exactly a Deja vu , it’s a feeling of familiarity or a feeling of recollection .

There are many theories regarding this phenomena like

1: Sense and memory mix up or Familiarity-Based Recognition or
The Hologram Theory

all these theories basically point out that we can recall information better when placed in the same environment in which we studied it. Any Stimulus like smell sound or a picture can trigger Déjà vu

But my personal favorite is this : Parallel Universe Theory

this is the only theory which is not backed up with any Scientific proof or explanations but this particular theory amazes me the most .
Basically in Quantum Physics its said that there is no past or present or future
everything is running parallel .
The idea that we live among millions of parallel universes containing millions of versions of ourselves carrying out our own lives with a diversity of different possibilities has always been a somewhat exciting thought. Déjà vu could actually contribute to this theory!

Believers in this theory claim that the human experience of deja vu can be explained by considering the unsettling feeling of having lived a moment before as a “crossover” with a parallel universe. This would mean that whatever you’re doing while experiencing the deja vu, a parallel version of you is doing it in a different universe simultaneously, therefore creating an Alignment between two Universe

Although intriguing, this theory is not backed with much scientific evidence, which makes it difficult to accept. However, the multiverse theory, which states that millions of universes form randomly side by side with only an exceptional few forming with the accessories to support life like ours, could help to assist this hypothesis.

Réponse d'origine: What is "deja vu" and what is the cause?

A2A

Theories include: Synchronous mental processes that become disrupted, neurological blips related to seizures, failures of memory, and split attention. All content below from a 2003 SMU meta-study reviewing various déjà vu studies*. All emphasis and organization is mine.

General Facts About Déjà Vu:

67% of people have had a déjà vu experience (a median of 41 surveys).

The most consistent finding in the déjà vu literature is that the incidence with which it is experienced decreases with age.

Two sets of outcomes suggest that belief in, or acceptance of, the déjà vu experience has increased across recent decades. Gallup and Newport (1991) found that from 1978 to 1990, the amount of people who believed in the de´ja` vu experience nearly doubled from 30% to 55%.

A positive relationship between the déjà vu experience and both education level and socioeconomic class has been noted in both anecdotal and empirical evaluations... Palmer (1979) noted the lowest incidence of déjà vu (48%) at the bottom rung (grade school only) and the highest incidence of déjà vu (81%) among those with a graduate degree, ... [and] found the highest incidence of déjà vu among professionals (80%) and the lowest incidence among blue collar workers (50%).

Logically, those individuals who travel should have more opportunities to experience a déjà vu because they encounter objectively new physical locations more often than those who do not travel. Several investigations support this speculation.

Dual Processing EExplanation

The first category of déjà vu explanations is based on a disruption in the normal operation of two separate but interactive cognitive processes. At the core of each speculation, two mnemonic processes that generally operate in concert occasionally become asynchronous, or one process becomes activated in the absence of the other.

Gloor (1990) proposed that retrieval and familiarity are independent cognitive functions that usually operate in a coordinated manner, with recall accompanied by a sense of familiarity concerning the information retrieved. However, these two processes occasionally operate independently of each other. Thus, retrieval can be activated in the absence of familiarity, which causes an ostensibly familiar setting to become momentarily unfamiliar (jamais vu). Conversely, a familiarity response may become activated in the absence of retrieval (déjà vu)

Another dual-process interpretation, proposed by Bergson, is that perception and memory are simultaneous events and that “memory is never posterior to the formation of perception; it is contemporaneous with it. Step by step, as perception is created, the memory of it is projected beside it, as the shadow falls beside the body” (as cited in Carrington, 1931, p. 303; cf. Tulving, 1968). People’s cognitive resources are generally focused on the perception of an ongoing event, but distraction, inattention, or fatigue can lead to memory and perception momentarily enfolding in on each other. Bergson likened this to two soldiers marching in tight formation: If the first one pauses for a moment, the two will bump into each other. Thus, if storage of information occasionally occurs the moment it is perceived, it could give rise to inappropriate recognition or déjà vu.

Merci
