Can someone tell me what exactly a deja vu is and what causes it.?

Answer 1

deja vu is a condition, where you feel like you have been there before. The exact situation you are in presently happens again. Scientists have put forth the idea that actually what is happening is that people are experiencing a temporary black out and when they come back to present time they feel like they had not left but were always there.

Answer 2

Neo: Whoa. Deja vu.

Trinity: What did you just say?

Neo: Nothing. Just had a little deja vu.

Trinity: What happened? What did you see?

Neo: A black cat went past us and then I saw another that looked just like it.

Trinity: How much like it? Was it the same cat?

Neo: It might have been. I'm not sure. What is it?

Trinity: A deja vu is usually a glitch in the Matrix. It happens when they change something

Answer 3

The term "déjà vu" (French for "already seen", also called paramnesia) describes the experience of feeling that one has witnessed or experienced a new situation previously. The term was created 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 French concentrator at the University of Chicago. The experience of déjà vu is usually accompanied by a compelling sense of familiarity, and also a sense of "eerieness," "strangeness," or "weirdness." The "previous" experience is most frequently attributed to a dream, although in some cases there is a firm sense that the experience "genuinely happened" in the past.

The experience of déjà vu seems to be very common; in formal studies 70% or more of the population report having experienced it at least once. References to the experience of déjà vu are also found in literature of the past, indicating it is not a new phenomenon. While it has been extremely difficult to invoke the déjà vu experience in laboratory settings, therefore making it a subject of few empirical studies, recently researchers have found ways to recreate this sensation using hypnosis.

Answer 4

Wrong section, but whatever.

Basically, your brain has LOTS of pathways in it. When you see/hear something, you get a signal that lets you interpret, that is, actually see/hear, that data, and also one that encodes that data into your memory. But these pathways are constantly being used by other parts of the brain. So if you're using the pathway that lets you interpret data for just a split second, you will have a memory of what you see/hear before you actually think you see/hear it. So you feel as if you "knew" that was going to happen, although this is not the case.

Answer 5

It's a MIND ECHO. A vision you have in your head that will bounce from right hemisphere to left hemisphere several times. neuro-synapses or swithes in your head are supposedly resetting, rebooting if you will and this will cause a thought to bounce from one side of the brain to the other giving you the sensation that you have lived that moment before or at some other time.

deja vu means I am doing it again. I have been here before.
So when they say that they mean it feels like I have been here before.

Answer 8

It's a feeling that events happening now have happened before.

I think it is a type of glitch in the human memory.

It could also be a result of recalling by any of ones physical senses or sixth sense or God sense.
