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.
Other Spiritual Perspective: As many people even remember the word to word conversation occurred in the dÃ©jÃ  vu, thereâs a chance then it is the form of any psychic phenomenon like clairvoyance, precognition, etc.
