🔮 Symbolic Approach
The sea represents the unconscious, the vastness of emotions, and the cycle of life-death-rebirth. A calm sea = inner peace; a raging sea = overflowing emotions or events.
🛋️ Psychoanalysis (Freud & Jung)
For Freud and Jung, the sea is the collective and personal unconscious. Swimming in it = immersing in one's emotions; staying on shore = staying on the surface for fear of drowning in feeling.
🧠 Neuroscience
Water and the sea horizon are associated with states of calm or openness. The brain associates the sea with vacation, letting go, or natural power depending on the dream context.
💡 Practical Advice
Look at the state of the sea in your dream. It often reflects your emotional state. It invites you to connect to your emotions without getting lost: find the right balance between immersion and distance.
