Dunno about deja vu, but I get a fair bit of jamais vu these days ..
It's well documented that such a thing can have a neurological cause. Someone pointed this out at the forum you linked to, but it bears reiteration: Deja Vu is a common manifestation of a simple partial seizure, which is any seizure activity limited to a small area of one hemisphere. In the case of Deja Vu it is limited to the area around the hippocampus, which is a part of the brain essential to forming memories.Vladimirr said:My neurologist says it's likely tied to some other existing neurological issues that I have. The human brain is a very complicated device and can even fool itself about what it thinks it's experiencing from each of its inputs. Obviously not everyone who gets deja vu has a strong negative physiological response afterwards, but it does show that such a thing can be caused by a neurological event of some kind. Occam's razor would seem to apply here.
No, I haven't. Probably higher than average.chhitiz said:have you taken a proper IQ test, if so what was your score?
No, I haven't been diagnosed, have never had any reason to get a diagnosis.chhitiz said:have you been diagnosed with an autism spectrum disorder by a proper psychiatrist?
No, have no self-diagnosed myself to having any kind of autism.chhitiz said:have you self diagnosed the above but no had professional diagnosis till now, or been denied the possibility by a professional?
No, I'm quite social.chhitiz said:have you improper social skills?
Not really. Unless having a keen understanding of maths is considered creative.chhitiz said:are you creative?
No.chhitiz said:would you call yourself an out of box thinker?
Unless the person is a jerk or pushes my wrong buttons I'll be warm and friendly. I meet people with a positive attitude.chhitiz said:r you cold and impersonal or warm an friendly?
No.chhitiz said:do you have migraines? or what they call as ice-pick headaches? do you regularly have seizures?

What you describe isn't a deja vu, though. You are describing how real life events somehow manage to trigger the memory of a dream you'd forgotten. It also wasn't a "prophetic" dream. You'd merely dreamt of a "similar" parking lot. Your chances of encountering a parking lot are so high it's not surprising you'd end up being reminded later if you had a dream about one.mnb96 said:I had to tell my friends I was having an "unusual deja-vu" :)
No, you didn't have the feeling of certainty of having lived through it before, you recalled that you'd dreamt something similar the night before.mnb96 said:@zoobyshoe:
I cite from Wikipedia:
"...Déjà vu (French pronunciation: [deʒa vy], literally "already seen") is the feeling of certainty that one has already witnessed or experienced a current situation, even though the exact circumstances of the prior encounter are unclear and were perhaps imagined..."
This perfectly suits the personal experiences/feelings I have reported.
I am not confusing deja vu with premonition. The link is made in the OP with the suggestion that deja vu is caused by a prophetic dream: you dream of the future, then it comes true, hence, a weird feeling of familiarity. Anecdotes to the effect, "I dreamt something, then it came true" would fit this theme. Your anecdote doesn't really tie in.I am no expert in this field, but as far as I understood the concept of Déja vu does not involve any "prophetic" aspect, as you claim. Are you sure you are not confusing Deja vu with premonition?
It's interesting, yes. I'm concerned about the term "deja vu" getting conflated with similar sounding things that aren't actually deja vu's.About my dream of the parking lot, I agree with you when you say that "the chances of encountering a parking lot are so high it's not surprising you'd end up being reminded later if you had a dream about one". In fact, I used carefully my words and I talked about simple "coincidence". What I found surprising was mainly the fact that I was suddenly able to recall for the first time a dream that I had two years before and that I had never been able to recall previously.
zoobyshoe said:A deja vu is never a true memory: it's a neurological illusion. You can't remember the present. Remembering a dream you had is a true memory: you actually had the dream at some point in the past.
It's paradoxical and calls attention to itself for being paradoxical: the present has the feeling of being from the past, but you can't link the scene to anything but itself. You are aware the present is reminding you of the present! I used to think of them as "Phantom Memories of the Present". The best "test" of a deja vu is: if the explanation that you have been shoved slightly back in time to relive a moment exactly, is the one that seems to make the most sense. You are always struck by the knowledge it's paradoxical: you can't have experienced the present before, but it seems so powerfully familiar, more familiar, in fact, than authentically familiar situations ever seem.mnb96 said:This sentence was particularly helpful. And apparently these concepts are more subtle than what a casual reader like me is usually led to think.
So, basically what you are trying to say (please, correct me if I am wrong) is that an essential ingredient for one experience to be regarded as a deja-vu is the strong feeling of having experienced the same thing in the past, combined with the impossibility to recollect the actual memory of it (if such memory exists at all). Did I get it right?
You didn't report any " certainty of having lived through it before" when you told the story, though.I am still a bit puzzled at why you insist that my experience (although admittedly not very interesting) does not fit the definition of deja-vu. You claim that my experiences are not deja-vus because I "didn't have the feeling of certainty of having lived through it before". I actually I did have that feeling, but that feeling usually lasted at most minutes, until I realized that it was due to a dream I had previously.
I cite again from Wikipedia:
Déjà vu [...] is the feeling of certainty that one has already witnessed [...] a current situation, even though the exact circumstances of the prior encounter [...] were perhaps imagined... The "previous" experience is most frequently attributed to a dream [...]
