The sea is the unconscious in its grandest costume: vast, deep, beautiful and never fully knowable. A calm, sunlit sea reflects emotional spaciousness and peace with life's bigness. Swimming comfortably suggests trust in your feelings and ease within uncertainty.
A stormy or dark sea warns of emotional turbulence rising from the depths — grief, longing or anger too large to name yet. Drowning speaks of overwhelm; watching the storm safely from shore shows growing wisdom: feeling your feelings without being swept away. Folk tradition ties a bountiful sea to generous fortune.
