Residual feelings or uncertainties that you haven’t totally dealt with honestly or recognized.
Esoterically, the disembodied spirit of a person who has returned with a message for you, or to ask for your aid.
Something perceived as remote or unlikely (e.g., “ghost of a chance”). Memories of deceased friends, parents, and loved ones.
Undiscovered talents or portions of the self, especially those of a psychic nature. Jungian: Uncontrolled psychic forces or complexes.
Being possessed by a spirit: A neurosis or psychosis that overrides your normal actions and reactions. Alternatively, this dream may occur to someone who has a drinking problem as a warning not to let this spirit possess them.
A ghost town: This symbolizes a penchant for living in the past instead of fully handling the present.
The counsel here is to keep the good memories, let go of the rest, and start living fully again.
An omen of unexpected confrontation or trouble. [1]
