It has a window along one wall and a door opposite the window. One wall is painted green, the other three purple. It's room temperature (neither warm nor cold). There is a bed, a bedside table, a bookshelf, and a small desk. The ceiling light is small and functional.
The forest is dark. The trees are pine trees, tall and thin.
The path weaves through the trees. It is narrow and covered in leaves and debris, although it is perfectly clear where the path ends and the forest begins.
The water is a river, moving from my right to my left. It is wide and not particularly fast flowing. There is a rock in the middle of the river big enough to stand on. The water is a few feet deep.
It is a thermos filled with coffee. The thermos holds about two cups of liquid and is covered with a checked or tartan pattern.
It's a large, old fashioned key with big teeth. It is silver colored and slightly tarnished. It might unlock a dungeon or some secret chamber.
