Why do we have a sense of Deja-vu?

Question

I have it all the time but can't really understand why.

Remember, I am NOT asking "WHAT is deja-vu?"

No silly answers. Copy pasting from Wikipedia won't work for me. I want an answer in your own words.

4kidsmama - Really funny.

Isn't there a scientific explaination?

Hmmm...Everybody, I appreciate your sense of humour, but this is not the jokes category !

What are you talking about carlito. Huh. If you don't know the answer, simple...don't answer. It's not a compulsion.

And its NOT the jokes category. See properly !

Answer 1

.
Modern science does not have adequate explanations for it

Some suggest that some paranormal phenomena is at work.

Some remarkable cases seem to suggest Reincarnation…. The most famous is Shanti Devi, who was born in Delhi, India in 1926

A physiological explanation of the deja vu phenomenon suggests that the optical and neural paths from the two eyes may be slightly different. Or, perhaps, a "newer" and "older" brain processing method might be responsible.

It is possible that the déjà vu feeling is triggered by a neurochemical action in the brain that is not connected to any actual experience in the past. One feels strange and identifies the feeling with a memory, even though the experience is completely new.

Déjà vu experience may be due to having seen pictures or heard vivid stories many years earlier. The experience may be part of the dim recollections of childhood.

It is worth noting that the déjà vu feeling is common among psychiatric patients. The déjà vu feeling also frequently precedes temporal lobe epilepsy attacks. When Wilder Penfield did his famous experiment in 1955 in which he electrically stimulated the temporal lobes, he found about 8% of his subjects experienced "memories." He assumed he elicited actual memories. They could well have been hallucinations and the first examples of artificially stimulated déjà vu.

Answer 2

I believe we can't properly answer because we are 3 dimensional beings and Deja-vus deal with time which is the fourth dimension. We see time as less than it really is so the fact that we are seeing something that we dreamed in the past is not easy for us to accept. I've had some very powerful Deja-vus and I always remember the dream which caused it. Usually it is from a dream I had 6 months ago. Does that help?

Answer 3

I once heard that it can be due to recall error. For example sometimes something happens, we "recall" seeing that happen and think we have deja vu. However some scientists pointed out that it might be because we had been in a similar situation, or heard of an identical situation, but when we recall it, we unconsciously shape the memory to fit what we are experiencing right now, giving the false sense of deja vu.

However I'm not entirely convinced by this answer. It's very plausible, but it seems something is still missing. Just saying that "you remember it wrongly" in every case is not enough for every case. I guess sometimes it can be contributed to pure coincidence...

Answer 4

I know what you mean pretty much every day i have a sense of deja vu, but its really hard to explain. its wierd like i feel like i have been in that situation before but can't rememeber it some people would think its that you are reincarnated

Answer 5

As long as there are humans who have dreams, there will always be a sense of deja-vu.

Dreams and the psyche of people intertwine and our cognitive part never quite gets to grasp the connection. We are left only with a slight sense of familiarity when we get those quick looks at our inner self.

Relax, deja-vu is good for you. Enjoy it when it comes around-that is when you are closest to your inner being.

Answer 6

every time i've experienced deja vu i usually end up feeling like i've been in a similar situation before , maybe the same topic of conversation or something, and sometimes i also remember dreaming about the same thing i am experiencing deja vu about. i think its just supressed memories from your life, t.v., stories of someone elses experiences, etc...

Answer 7

Here is Most Perfect Explanation you ever seen, read or hear.

One possible explanation of déjà vu is that aspects of the current situation act as retrieval cues that unconsciously evoke an earlier experience, resulting in an eerie sense of familiarity.

Hope you understand :)

Answer 8

If you experience Deja-vu it's because you need more sleep. Your mind or brain specifically is unable to keep apace of what you are currently demanding of it. It is receiving inputs and it is unable to handle the experience in a normal time frame and because it has suffered a time lag it seems to the human mind to have experienced this once before. It just means you need some rest. It is not a complex para-normal mechanism.

Answer 9

This is the official medical answer.

Deja - vu occurs when there is a kind of 'short circuit' in our neural pathways.

When we see/ hear something, the electrical impulses travel along the corresponding pathways to our occipital cortex (where the brain makes sense of what we are seeing) or our temporal lobes ( where our brain makes sense of what we are hearing). These send the messages along another set of neural pathways to a part of our brain where we register (or become conscious of) what we are seeing or hearing.

This information then gets stored in our memory.

During deja-vu, the images/sounds travel to our occipital or temporal areas for 'decoding' and instead of getting sent back to our conscious brain for us to register along its normal pathway, it travels to our conscious brain via the pathways from our memory (jumps pathways), making it seem as if it is coming from our MEMORY , making it seem as if it has happened before.

There is also the opposite of deja-vu. It is called jamis-vu. This means when we see/hear something we have seen/heard before, we don't remember having ever seen/heard it before.

Answer 10

my explaination is :

our brain is big in size compare to other animals (i mean, not elephant). but the region/compartment/area we use is very very very very less. not even a few percent of total brain capacity. therefore these ppl r normal.

those ppl who hv this deja-vu or psychic power might due to the activation of certain part of the brain that we normally do not use.

i've read an article before saying that the reason why ppl say women hv better 6th sense, is when women r resting, a region inside the brain still active while this situation was not observed in guys while they r resting. maybe the active part of the brain enable them to RECIEVE whatever energy around them and SENSE something other ppl normally couldn't sense. these energy might be a dead person's memory, other ppl's experience...

maybe a deja-vu person SENSE something from his/her future memory???
