what exactly causes da-javu?

Question

no smart answeres its for a school project

Answer 1

There is a great article on deja vu in the latest New Scientist magazine. It is not online though. Basically it says that the brain sometimes thinks that it recognizes situations or people even if they have never seen them before. In other words, the brain can trick itself and have a sense of familiarity. I did find a link to the story, but you have to subscribe to the magazine to read the whole article. Try find the issue in a book store.

Answer 2

Déjà vu, French for "already seen," is the sensation of feeling eerily familiar with a newly encountered object or situation. It's that slightly jarring state of mind that can be triggered by any number of stimuli: a photograph, a phrase, a hand gesture. The sense that you've been here before.
Due to its ephemeral nature, there's very little scientific research on déjà vu. Although over 70% of people report having experienced the unsettling phenomenon, it does appear to affect people aged 15 through 25 more than any other age group. And according to How Stuff Works, it has been associated with temporal-lobe epilepsy. Some epileptics have reported feelings of deja vu that occur prior to and even during seizures.

Theories abound as to the cause of déjà vu. Simple wish fulfillment? A cerebral cross-wiring that confuses the present with the past? A pre-existing anxiety acting out? The subject is obviously still ripe for scientific and artistic exploration. Maybe time will yield an answer

Answer 3

It's actually spelled Deja Vu. No big deal. It's French and means "already seen."

Scientists really have no solid answers as to why this occurs. Frankly, nothing I've read has ever adequately explained why this happens, and what causes it.

It can be recreated through hypnosis, but never replicated in any other type of test. If scientists can't replicate it, they can't easily study and explain it.

Personally, Deja Vu creeps me out. I've experienced it many times, and it's always weird. How can I feel like I've done something before if I haven't? How can I feel like I know what will be said before it's said? Does this mean that people experiencing Deja Vu are somehow telepathic or precognitive? I don't know. But some 70% of people experience Deja Vu once or more over their life. As unique as that feeling is, other people also go through it.

My personal theory, is that our dreams may sometimes show us things to come. I know, it sounds goofy, but my mother has had several dreams that she told us about that later came true. I like to think that we might get a small glimpse of the future in our dreams, but who knows.

Answer 4

Deja vu (French: means "already seen" or "already experienced") can be caused by a sight, sound, smell or experience that you really did have before. It can also also be caused by a memory of something you read in a book, saw in a movie, or that someone told you about.

Deja vu is different than just a feeling of "hmm, this is familiar". It is often a physical reaction to feeling like you are in a repeated cycle of experience (that can be caused by any of the things above). Some people believe that strong experiences of deja vu that cannot be otherwise explained are caused by memories of a past life, or past lives.

Hope this helps!

Answer 5

I think dreams you had in the past ...or maybe you were there while you were younger and dont remember...but there are De-Javu's that feel just too weird to think of a cause...

Answer 6

Im sure it has something to do with the subconscience mind. our mind recognizes things based on feel, smell, sight, etc. sometimes there is a little glitch that makes it seem like we have done something before perhaps because those conditions were met. it feels wierd cause it only happens for a second or two.

Answer 7

first of all, it's spelled 'deja-vue' (french for 'already seen').

although no one really knows (or has proven) what causes deja vue, researchers believe that it is due to a momentary lapse in sensory reception .... i.e.: one or more of your senses takes in information about what is happenning, but your brain (for whatever reason) takes a second or two longer to process those observations into usable results. we end up thinking we've been through all this before, when in reality one part of the brain did it in real time and the conscious part is only catching up now.

Answer 8

Your brain linking real memories with current events.
Your brain linking dream memories with current events.
Your brain creating memories in real-time in response to current events.

Our brain is more advanced then the best computer out there. You store all data of everything you have ever expereinced in your brain forever. Our problem is most of it we can't access. Sometimes your brain will come up with some random data that you can't "put your finger on" and it will relate it to something that is going on, and you will feel like it had happened before.

Answer 9

There is usually a small lapse of time from when you experience something and when your brain records it. On rare occasions, your brain records things right when they happen, and this causes the sensation of deja-vu. It is like having a memory of what you are doing at the time.

Answer 10

They say it's from dreams that you don't remember. So when your dream comes true....it's a da-javu feeling.
