Not really sure, but i believe they are remnants of memories in your Brain that get activated if you see a special...something. You see lots of things every day, every seconds, and you forget most of it or save it in your subconscious. Then something triggers that hidden memory and you feel like you lived that scene before (you most likely did).


That's the boring answer. Paranormal activities are the other one.

A combination of imagination and memory, I would imagine.
You remember something similar, and your imagination alters the parts that do not mesh.

I'd also imagine the memories do not have to be of actual, physical events.
You could also probably have dreamed something similar, hence how you could have deja vu while doing something you've never done before in a place you've never been before.

Deja vu occurs when one half of your brain experiences something before the other half. You're effectively experiencing it twice in rapid succession.

according to wikipedia, its a lapse in your brain waves so you feel that you've experienced something twice.

Usually dejavu to me actually happens. Doesnt freak me out.

I'm pretty sure it's this. Either that or it's because of alcohol.

It's when your subconscious registers something before your conscious does, causing the feeling that you have experienced it before.

And I didn't even have to look it up!

I normally think that premonitions, and even certain dreams themselves are kind of a spiritual link to your past self or past life..

Sounds ridiculous, but still.

Usually when I have a deja vu I feel like I've dreamt it before, and in rare cases I can remember the age I was when I had that dream. E.g. I had a conversation with someone I met a year ago in a place I first went to a year ago, felt a sense of deja vu during the conversation and, at the same time, could remember dreaming of that moment 5 years ago back when I was in my old room. That's what really freaks me out

The most prevalent explanation is what the others said about something registering subconsciously before registering consciously, or something similar to that. There's no commonly accepted explanation for it though and no known cause. Being tired or anxious is kinda linked to it, but there's nothing solid on the matter.

I remember there was an interesting article in New Scientist about that, but you can just search for it yourself cos right now I cba :p

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


OT:

I've heard a theory that we already know what will happen throughout our whole lives, but we have to unlock it. We can unlock it through other means, but it is always unlocked as it occurs to us. In addition, sometimes when things take you unawares it taps into that knowledge pool and you subconsciously realize that you've always had the knowledge.

Another theory is a mismatch of information from your senses; if your mind has an image of a situation, and your ears register something before your eyes do, your mind will begin to update the situation based on what you hear before your eyes tell your brain what it actually looks like.

If your brain does a good job of predicting it, then you experience everything twice with a very slight delay, causing déjà vu.

Imagining that you've seen something before when you probably haven't. It seems so convincing though.

What the guys above me said.

But don't worry, I too get frequent and intense deja vu experiences.

And if you wanna be all mystical, you can always claim to have had a past life..

Simply put there are a ton of explanations both scientific and spiritual, the end result is that nobody knows (as uncomforting as that is) and truthfully I think Deja Vu hits differant people with differant levels of intensity as you can tell from some of the rather frank answers here.

I look at it this way, it generally does not do any direct damage that we have seen. What's more even if it was something really bad, it's not like I'm in any kind of position to do anything about it if I figured it out. Sadly that is the way it is for most of us. Speculation captures the imagination, but that's all it does.

Not using the search bar [http://www.escapistmagazine.com/forums/read/18.127175]. Also, a misfiring of neurons in the brain, making it feel like what we're seeing/hearing is a memory, without the feedback from any ACTUAL memory. That's why déja vu feels different from actually remembering something.
