(06/11/97)["Swimming up to Air."] I am swimming in very black, dark water. Some person, perhaps male, is with me. It is necessary to dive through a cavern where we will be underwater for no one knows how long. I am afraid but it must be done. I swim strongly for what seems forever and finally break the surface, gasping for air. I had reached the edge of my endurance. I see some brightly colored plastic objects floating near by and grab several to hang on to help me stay afloat. I swim around a circular shape. I am safe now
