The Bride is one of the antagonists in the movie, "Annabelle Comes Home", played by Natalia Safran.
It was first investigated by demonologists Ed and Lorraine Warren after a series of deaths involving grooms stabbed to death at their weddings. According to their case file, the Bride was a ghost that possessed an elegant wedding dress. After being purchased and worn by brides-to-be, the Bride possessed the human bodies and used them to kill their grooms with knives. After the event, the dress would mysteriously be clean of blood, returning to its untarnished white color for its next victim. Seven grooms were killed before the Warrens intervened, obtaining custody of the dress, blessing it, and keeping it locked in their occult museum at their house.
