Supposedly, deja vu occurs when your brain flubs the transfer between long term and short term memory, basically making you think that something you just did was something you've already done. My brain must be skipping like a record tonight, because I just had the longest, weirdest, most meta experience of deja vu I've ever had.
I'm writing a scene for "Black Edelweiss", one taking place between Konrad and Angela Petrelli. The deja vu moment kicked in as I pondered a specific line, and had a very specific image of the scene repeat on me. Then, I deja-remembered thinking about deja vu in the context of a deja vu episode. Then, it extended itself to Angela's presence in the scene, and the irony of deja vu occurring in a scene concerning a precog. And then, the moment finally concluded itself by misremembering the thought process which lead me to post about it here.
So yeah. Just another sign I should not be working on fic at ten 'til eleven when I have to get up early tomorrow for the first day of the quarter.
