Human: Produce a detailed written description of a spooky scene inside of a tunnel passage with a pile of blankets and rags. Assistant: 
The tunnel here is reinforced with heavy wooden boards that seem to be crawling with all sorts of vermin. A foul-smelling pile of blankets and rags in the corner and a lingering scent of something unwashed gives the impression that someone may have been using the niche as a hideout.
