Yeah you got the right idea, that's the same idea I had untill I looked up what a "Banshee" is, it's something from mythology and folklore
they are said to wail around a house if someone in the house is about to die, it's also said that There are particular families who are believed to have Banshees attached to them, and whose cries herald the death of a member of that family.
you can read more about it on wikipedia.
But yeah for the most part it does seem to be about what you said.
