The island in a dream indicates a woman to whom people seek refuge. Or it indicates a work to which a person resorts.

The island indicates a ruler or a scholar. Landing on it indicates security and comfort.

The island is interpreted as a rich woman. Whoever sees that he owns it will marry a rich woman.
