This dream is related within the mythic archetypes with death, and therefore some authors suggest it as ominous dream. However it can be interpreted following our role in the dream, in relation to the boat. Seeing the boat as it sails away, speaks of distances, goodbyes and seeing the boat reaching the coast may be reflecting that thing we expect with illusion. And if we are the boatman rowing with a lot of momentum that means we have to do our part if we wish to arrive at good harbor.
