A corpse candle or light is a flame or ball of light, often blue, that is seen to travel just above the ground on the route from the cemetery to the dying person's house and back again, and is particularly associated with Wales. A corpse fire is very similar as the name comes from lights appearing specifically within graveyards where it was believed the lights were an omen of death or coming tragedy and would mark the route of a future funeral, from the victim's house to the graveyard, where it would vanish into the ground at the site of the burial. The appearance was often said to be on the night before a death.
