Based off a dream I had not too long ago. I found myself in the middle of bleak looking concrete city, it was very grey and had towering dark skyscrapers. It was a huge city but it was abandoned, and looked really run down. Despite it looking futuristic-ish it had gravel roads that looked really cracked, and unused for years. There were no lights either aside from what broke through the extremely thick clouds, and the red ones you see on top of skyscrapers. It was a strangely vivid dream too and it seemed to last for a while and I just wandered this huge empty city I was alone in. Throughout the dream all I heard was the low howl of the wind, and the crunching of gravel beneath my feet as I trudged my way through.
