Should I go to a bigger city like Barcelona? There's too much noise around my city (and so does Barcelona) and I wouldn't be able to sleep more than 2 hours in broken sleep patterns.
I believe staying in Barcelona would be too dangerous for me since you can get your stuff stolen in those places (as I'll be carrying a hiking backpack) and violent migrants carrying knives usually target the homeless. I want to carry my phone as well since I have to read some stuff online and I might die out of boredom.
Well I don't know what you like. If you need quiet of course head out some place more remote.
I was saying a hidden spot.
You saying you literally hunted by Africans and look for you more than police?
Tent cities and homeless programs can be good depending on what you are looking for.
Find a place of worship that runs as 24/7 as possible. It can help with boredom.
