When you dream about ghosts, it might be a sign that your future is unsettled. Dreams are metaphorical and symbolic representations of what is going on in our waking life.
It could also mean that the dreaming person’s past experiences with these beings have left them feeling unsettled or frightened. It could also represent fear of the unknown, and general feelings of insecurity over a change in circumstances which they cannot control (e.g., major illnesses, financial stability).
