The feeling that you are doing something that you've already done before. Literal translation "already seen" (from
French,
deja 'already',
vu 'seen'). Apparently it's due to a blip in your brain process which gives you the illusion that you've been somewhere/done something before, and technically, you have - a fraction of a second ago.
However, a common misinterpretation of
deja vu is a repeat of a certain event. For example, in an episode of Garfield and Friends (US Acres) Orson perpetually removes the same book (
Deja vu: the feeling that you are doing something that you've done before) from a box of books over and over again. This is NOT
deja vu; rather, it's an event that doesn't have a forseeable end: an infinite loop, if you will.
If you walk into a room and immediately get the feeling that you've been there before, then that is a case of
deja vu.
When i stepped out the
door and looked at the sky, i immediately
felt like i'd forseen this. wow,
deja vu. looks like its going to be a very interesting day...
