I was sleeping wild
In Wroclaw I was staying for two nights in hostels. The third day the hostels and AirBnb rooms were getting full quickly. I tried to find a Couchsurfing host, however nobody was available. Since the weather was very hot in the evening I decided to camp outside the city. I found some nice forest and when I came there in the night I saw the light of a fire near a bridge. I joined a group of students there and when they came home I went to sleep near the fire. The only problem was I didn't have any tent or sleeping bag. So I just put my blazer underneath, put all clothes on and I was keeping the fire running. The lowest air temperature was 14 ˚C but the fire was warming the surroundings. It was a little harder comfort zone challenge but I chose it voluntarily. I only could not sleep, so the next day I had to sleep for 17 hours.
