I dreamed that I was with an older woman (perhaps in her 60s), who was leading me on some sort of swimming expedition.  We came across some stalagmite-type formations sticking out of the water, and my guide encouraged me to view them by partially submerging my face so that the top half of my eyes saw what was above water level and the bottom half of my eyes saw what was submerged.  I indicated that I already knew that the formations continued underwater, but she insisted that I view it for myself.  Afterwards, we swam toward a farther destination, and the experience of swimming was transcendently pleasurable.  I found that I couldn't sink and therefore could devote myself to swimming with absolutely no fear, much as a fish must feel.  The feel of the water itself was also astonishingly, transcendently pleasurable.  It had no temperature (neither warm nor cold), but I felt so at home in it that it bordered on ecstasy.  I felt wholly in my element, at one with the ocean, and enjoyed that swimming more than anything else I've ever done in my life.
