Dreams about water, especially clear oceans, often symbolize emotions and the subconscious mind. The ocean's clarity could represent a sense of peace or clarity in your life, but the fear of drowning indicates feelings of being overwhelmed or anxious about emotional situations or changes you might be facing.

The presence of sacks full of food suggests abundance and nourishment, which might signify your need for emotional or physical sustenance. As you are currently single, this could reflect a desire for connection or fulfillment in your personal life.

Overall, this dream may be urging you to confront your emotions and seek out what truly nourishes you, whether that be relationships, personal growth, or self-care. It might be beneficial to explore these feelings further and consider what aspects of your life need attention and nurturing.
