There are as many ways to interpret dreams as there are schools of psychology. One approach is to view everyone and everything in the dream as a representation of the dreamer. If you find your self running from a ghost you are both the ghost and the runner. No one system or approach is definitive. In therapy recounting a dream is a useful way to allow a subject to freely associate and interpret imagery without having to be logical. It eliminates obstacles like explanations or rationalizations and provides a free and open avenue for expression.
