What is the medical term for having déjà vu? (And what is the opposite sensation called?)

Déjà vu is that spooky feeling in which you feel like you have previously experienced something that is actually being encountered for the first time.

In French, the term literally means “already seen.” Déjà vu is often referred to as paramnesia, which is both “the illusion of remembering scenes and events when experienced for the first time” and also “a condition in which the proper meaning of words cannot be remembered.”

Have you ever stared at a word that you’ve seen thousands of times but that looks unfamiliar? This sensation is often described as the opposite of déjà vu. Jamais vu, is French for “never seen.” This psychology term is used to describe a familiar situation that the observer doesn’t recognize.

Déjà vu is also similar to a phenomenon called presque vu, or Tip of the Tongue. In French, the term means “almost seen.” It is a disorienting sensation of being on the brink of remembering something. When experiencing presque vu, people often say that they have something on the tip of their tongue.

Now, what do you call the state between waking and sleeping? (Here’s the answer.) And what do you call someone who wakes up in their own dreams? (Look here for that one.)

    I’m always forgetting what deja vu means. I’ve experienced a form of it; it’s like, I’m in a certain situation and I feel like I’ve dreamed that situation before. What would you call that? Just the other night I could not for the life of me remember the name of that guy with the big red beard and mustache and the pistols from Loony Tunes. It wasn’t until the next morning I remembered his name is Yosemite Sam. I guess that’s presque vu.

    My name is Cloverpaw and I’m a ThunderClan apprentice. My mentor is Cinderheart. She’s the best. When I’m a warrior I’m going to be the best hunter in the forest.

    I have experienced deja vu too. And one common jamais vu situation is I sometimes totally forget the spelling of “with”. I misspell it as “wiht”. Not a typo but….

    Years back I read a comment that one teenager posting his commnet that he did not want to reconcider his career at the age of 40, and I thought that that could be true.

    It would be easy to pack and leave for a new life at the age of 20, but I wonder what it would take to do that for one after two decades after.

    I don’t get deja vu lately but had ones more than a few times when younger–a feeling that a very familiar image run through my mind was from so distant back in the past but its sensation tells me that has just happened a moment ago for the first time.

    If one is caught up with the past, then deja vu comes upon one with a litte grip. One would be advised to extricate oneself from a twilight zone!

    Here’s a different twist on deja vu that I came across a number of years ago. To me it’s a legitimate alternative viewpoint. We all know that the majority of we humans have a left and right hemisphere of the brain, the hemispheres being “seperated” by the Corpus Collosum – a network of nerves and tissue. There was a study done about 15 years ago by two undergrads’, here is a brief description of their study on deja vu. There are times when some of us have “entered” a room or experienced some other event for the first time, for all intents and purposes I will stick with the “room”. When the room is “entered” we visually take it in seemingly simotaniously by the left and right eye and relayed to the visual cortex – their premise is this – the left may record (memory) the event a micro second before the right or the opposite may occur – right may record (memory) the event a micro second before the left. Either way there is the distinct possibilty that the split second has allowed “memory” of the event to occur. Let’s say the left side “saw” the room the split second before the right – as the left stimuli has entered and been recorded the right stimuli is just being recorded. Here in lies the rub – the right stimuli “clashes” with the already recorded left. This micro second split of memory may give the person the illusion of being in this room before. I hope you find this as interesting. I’m not positive on this but this article may have been in an old issue od Scientific American.

    A déjà vu happens when the Matrix had been changed.

    I usually do not like to be an alarmist, but I had intense Déjà vu for ten years. Turns out I had a benign brain tumor (oops)…I was told that tiny siezures in the brain cause that familiar sense of having done something before. Boo-hoo. Anyhow, I am fine now (knock on wood!).

    I wonder what to call a person who tries to be inconsistent to be consistent. A TA at my 247 philosophy class at Stony Brook years back told the class the name of Marcel DuChamp–a twisted hermaphorodite, that is what I come up with at best.

    This morning my wife said to me “Do you believe in premonitions?” I replied that I did not. She then said ” I saw both our mothers last night, I cuddled my own mother and never felt so peaceful in all my life.” (both mothers are deceased.)
    Is that Deja vu?
    Nonsense I feel.

    Which begs the question (as long as we’re being silly), I suppose, of why a perjurer isn’t called a pergeon.

    A thaumaturge works thaumaturgy, a surgeon doesn’t work surgy. If they did, they’d be called surgists. >_>

    I prefer to call it, déjà prévu,– Comes from watching a few minutes of a movie before deciding it’s not worth it but then wondering how much of it I previewed last time before deciding it was -then- not worth it….

    What do you call, re-re-re-reading a paragraph to get the right sense of it, until you can’t even focus on a single phrase to clear that much…?

    And, What’s the word for knowing that that can’t be the right spelling and therefor refusing to look it up because it won’t help?- Corpuscular and crepuscular are very different and you know you’ve seen one before.
    __

    Also, I looked-up the other-word, oneironaut, but don’t find the meaning of waking-up in one’s dreams, that is until you realize: that you’re not really awake and then wake-up and see that you were inches-away from the same position you dreamt you were awake in! (Oops: trailing preposition)

    This mode is often accompanied by ‘seeing’ sunbeams or even the sun-disk but in reality you should never look directly at the sun….

    THAT’S A BUG in the definition, I think.
    __

    And lastly– Howcome a thaumaturge is not a thaumaturgeon, like, surgeon?

    Ray.
