I'd say at least 40% of today was deje vu.
I've never had that high of a level of that feeling I've done all this before. Or at least had a dream about it.
And four times while I was talking to people I felt like I was not there at all. Like when I finished the sentence I had no idea what I said to the person I was speaking to.
What is your guys opinions on what exactly deje vu is?

Deja vu is (as far as is practically useful, and contrary to the definition) a false recollection; discernible due to its hallucinatory sensations.
Otherwise it is merely a spontaneous or associated recollection, which are entirely different and easily categorised sensations: bear in mind how repetitive our lives our; it stands to reason that we will, in fact, do exactly the same things multiple times in our lives; and when we do these things recall having done them before: because we did; thus, because this functions in no way different to other spontaneous recall, why give it a new name?
Supposedly it's because the RAM in your brain isn't keeping up with the pace at which things unfold before you, meaning your brain registers things a fraction after they actually happened.
Except for the last 6 words I agree with that.
The stuff I was doing today where I had that recllection was something I had not done before though.
Interesting. I;d buy that, particularly today where I had sensations of not knowing what I just said and disorientation.
SupremeAC pretty much nailed it. Though I heard it described in a very dumbed down way and it made total sense to the lowest common denominator (ME!!!!!!!).
Your brain is essentially a series of roads. Typically the way you percieve the present is the main highway. Every once in a while that highway has a back-up or is under construction so your perception has to take a detour through the backroads that is usually used by memory. The result is the perception of the present feels like a memory.
The original example actually incorporated stopping at a Dairy Queen for a Blizzard on that detour, and went into some more detail, but I assume everyone here already kind of gets that point, and I'm too lazy to type it all out. So there ya go.
The question demands elaboration if the answer provided is negative.
I would describe that as an entirely different sensation altogether.
Which is the problem with deja vu: it is as useless as "epilepsy".
Why is epilepsy useless?
In the sense that it also describes too great a range of things. However the majority of things that epilepsy describes are well defined and undisputed, so it actually is mostly useful.
