If you do dream of traveling in a boat, pay close attention to the conditions of travel as they will reveal much about your waking situation. Are the waters calm or is a storm building?
If the boat is drifting aimlessly on the water, you may feel that you are lacking direction, whilst if the boat capsizes, this suggests imminent danger or obstacles ahead.
If you are enjoying a tranquil boat ride that is slowly but surely heading in the right direction, this could imply a sense of anticipated success with a particular project in real life. A ferry is an archetypal vessel associated with transition from one stage of consciousness to another, and the ferryman is the archetypal wise old man.
If you dream of docks, this is a symbol of the safe ground you leave behind as you begin your voyage of discovery.
