Fire serpent

In Slavic mythology, the spirit that night in a ball of fire descends from heaven, enters the house and seduces women who takes things from other people's houses. "Scattered sparks" over the pipe, he (through the pipe) appears in the hut in the guise of a handsome guy or a friend of the husband of the mistress of the house (sometimes in the form of a recently deceased husband, if a widow yearns for him).

Women begin to dry, wither (the serpent like "sucks" them of their power, and sometimes even crushes, eats them).

It is indicated that the Transbaikalian peasants said:

"Gestated her [woman] of snakes, having grown up, is living with her. At night he flies, swinging from itself sparks of fire, and brings home mistress gold. But it is not necessary to leave the snake alive for a long time, otherwise it will suck from a housewife all of her blood, so when a dragon trained enough wealth to its owner, she needs to leave him sleepy in the fiery furnace and burn" <Loginovsky, 1903>

And Zabaykalsky believed that the fire dragon is a negative aspect of a house/yard of the spirit: he brings home the wealth, but wealth is fragile, dangerous (Kursk, Vologda):

"If a man wants to get rich, he needs to obtain an egg from the rooster and carry it around six weeks under his left arm, after which the eggs hatch snakes. The night here must lie in uninhabited hut, where there are no icons, for example in the bath. In the dream, the devil is inferior to serpent for a certain period, on certain conditions. The fiery serpent is the man the money, they are going on drinking... When the time comes, you can still be saved, cut the "snake" vein under the neck. And the man and the serpent, knowing this, are hanging in there, but rarely the person overcomes the serpent. More often he dies, pierced through the flames of hell snake"

Often the appearance of the fiery serpent means a quick death on the roof he lands.

*you can find references from historians that sparkling fiery snakes often called comets and meteors.
