Sea cliff
A sheer drop from land into sea — a hard, definite edge between two worlds.
A sea cliff in a dream is the dream's image of an absolute edge — the place where the land ends and the ocean begins, with no gradual transition. The dream brings the cliff when a hard line in your life — between two phases, two loyalties, two versions of yourself — has become clear and is no longer something you can shade or compromise. A sea cliff stood on with the wind at your back is the dream telling you the boundary is honest and can be respected. A sea cliff approached blindly, with the edge hidden by mist, is the dream warning that an absolute end is much nearer than your current pace assumes.
