Sorry forgot a couple of points... shops will be closed on Bastille Day and the fireworks kick off after dark around 10ish. Trocadero is the best place to watch them but people start congregating there late in the afternoon / evening so it will be busy busy busy :o)
DÃ©jÃ  vu (/ Ë d eÉª Ê ÉË Ë v uË, - Ë v j uË / ( listen); French pronunciation: ( listen)) is the feeling that the situation currently being experienced has already been experienced in the past.
sometimes these deja vu's occur in dreams. one may dream of something that at the time makes no sense but days, weeks, or months later, it happens and it all of a sudden hits you. oh my goodness that's really freaky, i just had a deja vu. months ago i think of dreamt of exactly what just happened.
