This is a thing that I did not know was happening in Barcelona today when I booked our trip "The correfoc represents the driving out of evil spirits and symbolises the triumph of good over evil with the patron saint providing protection over the city. The fire and noise is believed to purify the strees. The Devils are cultural groups that dress up as devils and parade the streets during certain festivals in Barcelona. La Mercè is one such event. The devils run up the streets with bangers and handheld fireworks. Lots of bangs and fire is the order of the day. Fire breathing dragons (or at least sparkler-breathing dragons) also roam the streets with Devils skipping along with spiralling fireworks held in their hands." So should I be relieved that I will have all my familiar demons driven out of me, or concerned that new demons will ensoul me? As an atheist who hates crowds and especially fireworks, this might have been bad planning on my part https://www.barcelona.de/en/barcelona-la-merce.html
