In my dreams, the ocean has this great hulking presence. I sense it’s awareness. The best image I can conjure is that of a big, pulsing brain.
Note: I’ve read that the ocean usually represents the unconscious, or possibly the collective unconscious. Some interpret it a symbol for a source of divinity. Those are both valid points. A more personal meaning could relate to a sense that I have, that there is a sea of life and energy that we are a part of, and we are like a drop in the ocean, changing form, never disconnected, really..
