Influential Disaster

I'm on a beach celebrating something, but I keep watching the shore. The waves look so strange, rolling and moving oddly. It takes me a short time to realize what's wrong and yell "Run!" By this time everyone else is running away from the shore. My youngest sister and I enter a building as water is already rushing around our ankles. I know we can't make it any higher without getting caught. I grab a metal rail and hug my sister close looking for something to help anchor us- just telling her to hold on as the waves engulf us. I remember taking a big breath and then nothing. Shortly after that we were both coughing up water and pulling dead leaves, twigs, and I think bugs from our hair. There was no euphoria of living, only confusion about what had just happened.
