Dream about sitting on a cliff is repressed emotions and feelings that you do not want to confront. You need to better focus your energies and direct them on your goals. You are still hanging to some part of your past and are not completely ready to move forward. It is an evidence for someone in your life who is giving orders at you. You may be turning to a potentially harmful alternative as an instant escape from your problems.
Sitting on a cliff dream signifies your overindulgences and excesses. You are holding onto a relationship that is dead. Things that come too quickly have a tendency to disappear just as quick. This dream denotes a bad habit or a certain food. You are feeling burdened by the responsibility of taking care of someone else.
If you dreamt about sitting on a cliff:
There is a metaphysical slant to your love life with the aspect at play today. Perhaps the person you meet at a party was a love interest from a previous life with whom you shared many adventures together. Whatever the scenario, you feel extremely glad to be in their company, as well as very relaxed. You feel as though they are your spiritual equal. There is a deep bond here.
