Kajtek's precognition post got me thinking about this sort of thing. I am sure you are all familiar with Deja Vu, as we have all probably experienced it ourselves. What strikes me as odd is the several times in my life where my deja vu has lasted for nearly a minute. Normally when I have deja vu it consists of only one event that lasts less than a couple of seconds, but in these rare cases, as soon as I recognize the deja vu, it continues and every sequence of it I have seen somewhere before -- as far as I know in my dreams. Each time this has happened, which is certainly less than I can count on both hands, the experience has left my heart pounding and me feeling sick to my stomach. Has anyone else ever experienced such vivid deja vu, and if so please explain to me what it could mean. The only reasonable explanation I have come across is that I was hallucinating.
