To be adrift (sent out of home without anything) in the dream, is an obstacle dream, telling you of a problem you have been unable to solve, or unwilling to tackle.
If it involved a boat or ship, and you reached land safely, you will overcome your difficulties.
If you fell out of the boat or ship in the dream, or was upset by rough weather, it portends serious warning of difficulties ahead due to indecision.
If you were rescued in the dream or managed to swim to safety it suggest, success and joy will follow your suffering.
