I'm sure many of us heard of ghosts and other supernatural creatures being omens of death or impending doom, like for example 'family' ghosts that appear to when there's an impeding death or disaster to the family they're 'attached' to, etc., but I was wondering if there are any ghosts that appear or are omens for good luck or joyous occasions?
I have a story where a family has a 'family ghost' that only appears to the future brides of the sons in the family (meaning a girl sees this ghost, in the near future she's going to end up married into the family). I was wondering if there are something similar in real-life ghostlore. It doesn't have to be exact, though, and ghosts that herald good luck or joyous occasions are most welcome.
I've google castle hauntings, ghost brides, bride omens, ghost good omens, etc., but haven't seen much so far. The nearest I could find was the Piper of Culzean Castle, where whenever one of the Kennedy (not the political one!) family is about to get married, a ghostly piper is said to play in the grounds. He is also supposed to play on stormy nights - mixed in with the howling wind and crashing waves.
Thank you. :D
