Entering the ocean is clearly a confrontation with many fears – the fear of what lurks in the unknown, of encountering beings that operate in apparently entirely different ways from us – creatures that exist as colonies rather than individuals, that have the ability to ‘breathe’ in water, that have teeth and all sorts of other weaponry we don’t understand – fear of entering into murky waters, fear of being immersed in an element that moves so differently from those we are more accustomed to, fear of getting frozen to the bone in cold waters, fear of getting swept along by unpredictable currents. In a very real sense, the ocean is a symbol of the human subconscious, and our fear of it mirrors our fear of what we don’t have conscious control over in our inner landscape. The ocean is the home of the shark – perhaps the creature that most potently embodies that which humans archetypically fear.
