A domovoi (Russian: домово́й; literally, "he of the house") is a house spirit in Slavic folklore. Domovois (the Russian plural form is domoviye) are masculine, typically small, and sometimes covered in hair all over. According to some traditions, the domovoi take on the appearance of current or former owners of the house and have a grey beard, sometimes with tails or little horns. There are tales of neighbours seeing the master of the house out in the yard while in fact the real master is asleep in bed. It has also been said that domovoi can take on the appearance of cats or dogs, but reports of this are fewer than of that mentioned before.
I think my apartment building HAS domovoye. They live in the bowels of the airshaft and blow cold, cigarette-smelling air at us through the silverware drawer. They also play "music" on bedsprings when the wind blows. Sometimes after we make them offerings of old boots and milk, they stop blowing cigarette smoke at us and blow incense instead.
