The ferry combines the idea of public transportation (moving with the crowd toward conformity) with being on a ship (exploring emotions and feelings.) If you are waiting for a ferry, you may be too concerned with the idea of acceptance and are not able to express your real feelings. Since you are waiting, you may be giving the power to be fulfilled and autonomous in life to others, or to the whims of fate. The message might be to stop expecting and take responsibility for how you feel.
