The moss people or moss folk (German: Moosleute, "moss folk", wilde Leute, "wild folk"), also referred to as the wood people or wood folk (Holzleute, "wood folk") or forest folk (Waldleute, "forest-folk"), are a class of fairy folk, variously compared to dwarves, elves, or spirits, described in the folklore of Germany as having an intimate connection to trees and the forest. In German the words Schrat and Waldschrat are also used for a moss person. (Compare Old Norse skratti, "goblin".) The diminutive Schrätlein also serves as synonym for a nightmare creature.
