The Deposed Governor
Scholars have said that if a deposed governor sees themselves riding a ship, it may indicate their appointment to a new position by the supreme ruler, proportionate to the size of the sea and the ship's capacity. However, if the ship sinks, this may signify the ruler's anger towards them, but they may ultimately be saved and return to their position.
