A Watery Internment

You sink slowly As murk dissolves the luminance
 As pressure builds As flails reduce to flutter
 Lungs fill with fluid As breath stifles As panic
 Nictates into stillness With each weakening
 Dying heartbeat you grow closer to death
 What ideas enter a dying man's consciousness
 In those last moments of actuality?
 When survival is futile do you think of regret?
 Do you beg for forgiveness to a god above?
 An uncaring deity who let you suffer this fate?
 Deeper You've lost sense of direction Do you struggle
 To hang on to those last few moments of animation?
 Where minutes dissect into seconds
 Then seconds fraction themselves away into
 Closing flickers of existence The hourglass reduces to the falling of each individual grain, and the world around you is slowly engulfed in darkness... while you expire at the speed of thought
