crocodiles and water rising

I was in a room under my family home. The ocean was just outside, waves encircling the house and rising fast. Soon the water gushed into the house and many people swam out into the sea, meeting the waves head on. Rather than venture out, I swam through the now-open glass sliding doors and climbed on top of a corrugated iron shed to watch the crowd. I was eating dates. A crocodile swam out of the shed and into the ocean. I knew that my family were somewhere in the waves and I hoped that they would make it back alive. Twenty or more crocodiles emerged from the shed and powered out into the waves. One huge crocodile lurked below, circling the shed. It reared up out of the water and snapped giant jaws at me. I threw a date in its direction, which distracted the beast long enough for me to leap off the shed into the water and swim back into the house, where the water had now subsided. I closed the doors. After a time, the survivors of the sea left the water and began a long march away from the ocean. The caravan moved steadily, with purpose, the well aiding the injured. I ran through the crowd, searching for my family, and found my mother being carried on a stretcher by a few of her close friends. To my horror, I saw that her hands and her feet had been dismembered, but she had them with her. She seemed to feel no pain and, in fact, was quite happy, confident that her hands and feet would be reattached. She asked me to look for my father. I ran back along the line until I found him, sitting on a hospital bed watching the crowd file past. His legs had been bitten off and he was hooked up to a drip and another monitoring machine. I was devastated, but again he appeared not to be in pain and was sure that it would all turn out for the best. My brother appeared, also searching for family, and we wondered what to do. We were discussing the cataclysmic event and how each of us had done our best to survive it, when again the waves rose and crashed around us. With no time to lose, we unhooked my father from the various tubes, grabbed the hospital bed and pushed him through the waves, joining the procession away from the ocean. I wondered where my sister was and hoped we would find her.
