Mournful wail predicts death of kin

Banshee

The Banshee, a haunting figure from Irish folklore, is a female spirit known for her mournful cries that herald the imminent death of a family member.

Domovoi

a Domovoi seen weeping was said to foretell death in the family, while one seen laughing or dancing foretold celebration.

Melusine

In some tellings Raymondin's public denunciation of her as a serpent, rather than the spying itself, is what finally exiles her; upon the vow's violation she transforms fully into a winged serpent and flies from the castle, though she is said to return invisibly to nurse her youngest children at night and to reappear, shrieking, over Lusignan to foretell the death of a lord of the line or an impending change in its fortunes.

Gwrach y Rhibyn

Some sources describe her crying out specific, personal words depending on who is fated to die, such as calling out for "my husband" or "my wife" or "my little child," while a wordless, inarticulate scream is said to mean that the death foretold is that of the listener personally.
