Deja vu is an uncanny feeling or illusion of having already seen or experienced something that is being experienced.
It can be a illusion or delusion.

and dreams are related to our sub conscious mind. sub conscious looks at what happens the whole day in his own way and then sees it in dreams, or your hidden fears or feelings might come as dreams.

Dreams are very complex process and are not fully understood by scientists. but there r drugs that can give u good dreams and also which can give u night mares.

It seems that scientist got a new toy with which to study our dreams. It's called polysomnograph and it developed a particular area called polysomnography. A polysomnographic test can easily monitor the phases of your sleep, tell if you're having a nightmare or a pleasant sleep and determine whether you suffer from from sleep disorders.

(sorry for being offtopic, I thought it would be nice to mention this too)

Yeah, that's a little offtopic but it's interesting to know about it.
Thanks 4 the info!

I've noticed the concept of Deja Vu often gets associated with the idea of reincarnation, but then, the Bible mentions Deja Vu in the sense of dreams foretelling the future but also denies the idea of reincarnation, saying "it is appointed unto men once to die, but after this the judgment". (Hebrews 9:27)

All through the Bible God used dreams to tell people about events in their life to come.

In some cases, those not walking close to God needed their dreams explained:

-Joseph interpreted the dreams of Pharaoh and his servants to predict the fate of both servants, and of a 7 year famine to come (Genesis 40-41)

In some of those cases, the dreamers did not even tell the interpreters what the dreams were.

-Nebuchadnezzar, king of the Babylonian empire (which has been extensively verified by archeology), had a dream, but had trouble remembering it afterwards. He ordered his astrologers, magicians, and diviners to tell him what the dream was, but they claimed no man on earth could do such a thing. Daniel ended up telling him the dream and what it meant, a vision of future world empires to come, after first stressing that it was God who revealed it and that he Daniel had no ability of his own to do so. (Daniel 2)
-Nebuchadnezzar had another dream, but this time foretelling 7 years of insanity to come upon him for continuing to rebel against God. And afterwards, Nebuchadnezzar turned towards God and admitted his pride and God's justice in doing so. (Daniel 4)

In this case, dreams foretold future events to come in the life of the one dreaming of them:

-Joseph dreams that one day his brothers and parents will bow down before him, only to have it fulfilled later in his life when he is placed in authority in Egypt. (Genesis 37)

Admittedly, however, the Bible more often speaks of dreams being used by God to provide direction and guidance so people will make the right choices. God always seems to have a purpose in using dreams to foretell the future, and doesn't just use such 'deja vu' tactics for no reason.

-God uses a dream to let Abimelech know Abraham is being deceitful in not admitting Sarah is his wife, something Abraham did because he feared for his life and did not trust God, only one of many cases where the Bible speaks of godly people making mistakes which they often ended up apologizing to God for or even being punished for. (Genesis 20)
-God uses a dream to let Joseph know he's being protected and his heritage will be blessed. (Genesis 28)
-God uses a dream to warn Laban not to speak good or bad to Joseph. (Genesis 31:24)
-God uses a dream to let Gideon know he will be successful in attacking forces that were invading Israel. (Judges 7)
-God uses a dream to offer Solomon a blessing - Solomon chooses wisdom. (1 Kings 3)
-God uses a dream to let tell Joseph of His plans involving the Messiah, and to take Mary as his wife. (Matthew 1)
-God uses dreams to warn Joseph and the magi of Herod's evil intentions. (Matthew 2)
-Pilate's wife has a dream of Jesus and warns Pilate not to be guilty concerning him, which advice Pilate takes, in a way. (Matthew 27)

see!if it is mentioned in the books, its got to be true
if science told us that if we use our minds hard enough we could move objects then hey, predicting the future is a child's work

i believe in deja vu, its a very interesting concept to think about. but deja vu only happens to me about 3 times a year O.o; is that alot? anyways, i would have dreams of driving somewhere, doing something on the computer and i would have the same nightmare every night for 4 days straight sometimes. but the whole driving and doing something on the computer thing happens to me alot >.> but when deja vu hits me its a feeling of confusion and i get disoriented easily. especially when i have deja vu whilst driving.

The experience of déjà vu is usually accompanied by a compelling sense of familiarity, and also a sense of "eeriness", "strangeness", or "weirdness".[/quote][quote]The term deja vu is French and means, literally, "already seen." Those who have experienced the feeling describe it as an overwhelming sense of familiarity with something that shouldn't be familiar at all. Say, for example, you are traveling to England for the first time. You are touring a cathedral, and suddenly it seems as if you have been in that very spot before. Or maybe you are having dinner with a group of friends, discussing some current political topic, and you have the feeling that you've already experienced this very thing -- same friends, same dinner, same topic.

Idk how many times i've had deja vu but it always happens when i'm in a scenic area

Like this past monday I was walking through the park with my dog and I saw a guy running past me and he was the same dude from my dreams..

--

I'm a really superstitious person so I don't think of deja vu as a brain twitch anymore.

On runescape I was doing my daily fishing routine and the same guy walks by me as always and I watch his pet Cat run behind him and then I realize i've been in this situation before and I look around to see if there's anything the same around as before

I can't really explain the whole phenomenon but it freaks the crap out of me and then I have to sprinkle salt in water and drink it and the whole shebang!

Well I personally have dejavu multiple times. Usually I dont realize until its too late to keep it from happening. One time I realized that I was having dejavu and I could literally say everything that was this man was going to do before e did it. It was so creepy. I think that dejavu is a premonition of the future and we dont remember it until it is happening.
