Ghosts dream meaning

In this dream is a very important matter the color of the gown or robe the ghost has, and if this ghost has the appearance of a family member or ancestor. If so it can be a dream in which we are warned of a danger. If the spectrum is unknown but the ghost is wearing white robes, many authors agree that this is an omen of welfare, but if the robe is black, then the dream is warning us of treachery.
