25 parties and afters for a Halloween weekend of revelry and terror in Paris. Clubs, docks and warehouses turn into haunted houses: strobe lights, thick smoke and bass heavy enough to rattle your bones. Vampires, zombies, witches and fetish creatures take over the dancefloor, so costume and make-up are a must. Until the early hours, we scare ourselves, lose ourselves and dance like it's the last night of the living.
