Jamais vu involves a sense of eeriness and the observer's impression of seeing the situation for the first time, despite rationally knowing that he or she has been in the situation before...Jamais vu is most commonly experienced when a person momentarily does not recognise a word, person, or place that he or she already knows...I only bring this up because I have been experiencing this lately!
Or am I just losing my brain cells?
Incident 1: I have an opal necklace that I frequently wear (Jeremy bought it for me as a graduation present). A couple weeks ago, a coworker admired the necklace,and asked if it was opal. I hesitated, because suddenly, I was no longer sure it was an opal. Part of me rationally knew that it HAD to be, but it just seemed....wrong. I kept thinking opal sounded like the wrong stone, and every time I said or thought of the word, it generated an image of a fake pearl. For days afterwards, I tried to recall exactly what the name of the stone was, even though my brain kept screaming, It's OPAL you moron!!!
Incident 2: My favorite news anchor is Shepard Smith. Although I don't get to listen to his program that often (it conflicts with my work schedule), he has been my favorite news anchor for several years now. During the aftermath of the recent Boston terrorist attack, I was listening to the news in my car, and the news reporter stated, "And now we take you to Shepard Smith, who is in Boston..." Suddenly, "Smith" sounded incredibly mistaken. In that moment, I had the feeling that his last name HAD to be something else, because it couldn't be "Smith."
Incident 3: I was in the car (again), listening to the radio. The song "Bittersweet Symphony" came on, and that's when this jamais vu crap hit me again. I was mentally snagged on the word "bittersweet." This time, it actually was a good feeling though. I was turning the word around in my head, marveling over the simplicity of it, and wondering why the English language didn't jam other contradictory words together, like "darkbright" or "nearfar."
This feeling has hit me several times even prior to these incidences (which I believe is the case for many people). I remember several years ago, when I had been up writing an essay for hours, I suddenly started to doubt the spelling of the word "the." In that moment, I was convinced I was misspelling it. I also recall a couple times repeating a word out loud over and over and OVER until the word lost its meaning and I started to doubt whether the word even existed. Wikipedia describes this as "brain fatigue".
