Some believe that the ghosts in their dreams are real representations of the dead.
This is an unlikely explanation of this dream.
More likely the ghost is representing a part of you that is unclear and that you do not understand.
At times, ghosts represent those things that unattainable or fleeting.
Demonic type of ghost images may represent your negative tendencies, unpleasant parts of personality or your “shadow.” Old superstition based dream interpretations say that dreaming of friendly ghosts is a lucky omen, and that you should be receiving unexpected good luck.
On the other hand, if you were very frightened by the ghost in your dream, then others will try to impose their will on you and you must be vigilant in order to stand up to it.
