Dreams involving navigation, family, and water often carry rich symbolism. In your dream, using a map to search for food indicates a quest for sustenance—both physical and emotional. The 3D map suggesting disparities between rich and poor neighborhoods could symbolize your awareness of social issues or personal struggles regarding abundance and scarcity in your life.

The transition from land to a ship implies a journey or change in your current situation. Ships often represent emotional journeys, and being with family signifies support and connection. As you found yourself in Greece, a place known for its rich history and culture, it may reflect a desire for exploration or a longing for a different way of life.

The tsunami-sized waves represent overwhelming emotions or challenges in your life. They might symbolize feelings that are larger than life, which you are navigating through. The fact that you and your family got soaked but were unharmed shows resilience and adaptability in facing these challenges. Ultimately, finding food after this tumultuous experience suggests that despite the difficulties, you are able to find nourishment and satisfaction, both physically and emotionally.

This dream could encourage you to acknowledge the challenges you face while reminding you of your ability to overcome them with the support of loved ones. Consider reflecting on any current situations where you might feel overwhelmed and how you can navigate through them to find your 'food' or fulfillment.
