The cliff edge denotes a step off into the Unknown. A cliff equally can suggest an obstacle to be scaled. There may be a step we need to take which will psychologically put us either on edge or on the edge in such a way that we must overcome our own fears in order to proceed through our own limitations. To be on the edge of a cliff in a dream indicates the dreamer is facing danger. It shows the need to make a decision as to how to deal with a situation, and possibly be open to taking a risk. We are often facing the unknown. Consult the entries for Edge and Mountain for further clarification.
