The sea that appears in dreams means fantasy, adventure, one’s own dream, life as a whole, desire for adventure, etc. A dream of shrinking or drying up seawater is a dream that means worsening financial conditions symbolized by water. For example, you may go bankrupt or lose your job. Or it could mean mental instability, lack of affection and spiritual thirst, so you need to ponder what you really want and what you need.
