If you dreamed that you are standing on the edge of a cliff and experiencing fear, then in real life you are frightened by some unusual situation in which you need a decision. If you do not feel fear, then you will easily overcome all adversity. The dream in which you, being at the wheel, at a great speed break from the cliff to the abyss, means that in reality you got involved in a dubious adventure and now do not know how to get out of it. Fighting in a dream with a temptation to rush down the cliff can be a sign that your emotional experiences are too heavy for you and you are on the brink of depression. You need the help of a qualified specialist.
