You speak of basically a dead zone...The water goes flat as all hint of even a breeze vaporizes without the benefit of a swooshing sound. The cry of gulls creshendoed but ended with a single last trill. Silence hung as heavy as the air around without the benefit of movement. Even the clouds stopped, stilled in their tracks, with their wind swept swirls flattening out as the sea before them did. Nothing disappeared but the waves, the wind, the beach sounds, the cotton candy billows in the clouds. But then nothing appeared either like the sea gulls, waders, or even other people. All that I heard was was my own breathing, all that I felt was the beating of my own heart, and all that I saw was my own shadow.
