sea creatures

Walking through knee-deep water, ice blue and crystal clear. The body of water, though vast, seemed to be indoors, under a giant roof. Swimming in the water were all kinds of sea life: fish of many sizes and colours, small sharks, striped sea-snakes, neon jelly fish, florid sea horses, and nebulous life forms moving through coral and waving sea grasses.
Later, I was swimming in the ocean, way out at sea. The sky was grey and the water was immeasurably deep and dark. Fear crept into my body, rising within me. I scanned the water for shadows, sensing danger. With my mounting fear, I rose out of the water and found myself sitting on the edge of an old wooden jetty. From there, I could see several huge shadows moving through the water and I realised that I was surrounded by sharks and killer whales. The grey sharks remained submerged, zigzagging menacingly beyond the point at which the waves were breaking, whilst the black and white Orca jumped out of the waves, diving and dancing. Suddenly a killer whale leapt out of the water at the jetty, but a dolphin leapt with it and knocked it away from me, protecting me. I was delighted and, as the dolphin leapt out of the water again, I reached out and touched its skin, feeling it briefly as it descended back into the sea. A third time it reared up out of the water, but this time I could see that it had changed shape, that it was now a predatory shark, perhaps a great white, although not fully grown.
