Shared dream

I was at a friends house, which was somewhere in the country, sort of in the middle of nowhere...though the area was not deserted. They lived in a rural suburb of some sort...but the houses were built on cliffs and were old and crumbling. As we drove up to the house, we had to wind our way around a cliff face and I looking up and saw all these magnificent old houses in various styles of architecture: gothic, rococo, art nouveau...and it looked as though they would fall apart at any minute. As though they had been battered by years of sand and wind raking against the cliff faces. I remember putting my hands up over my head to avoid getting hit with anything that might fall. Once we reached the top however the land changed very much and became more flat, like the countryside. I remember being inside this friends house when everything just started flooding. The water was pouring in...it was clear, bright water...and I went outside and saw rivers of this gorgeous water flowing over all the land. We lost our footing and got swept up in the current. The water was flowing like a river over the roads, and it was several feet deep, as though some invisible barriers were keeping the water in the road. Once I hit the current I realized I was dreaming...and swam like a dolphin moving quickly with the water, through the streets...as they curved downwards, and went under bridges and railroad crossings. There were lots of other people in the water too, and they were sort of floating along like it was a lazy river. Then I noticed something dark in the water...it was coming after me. But what was it? It could swim faster than I could. I kept watching it, just thinking to myself that I could fly away if I had to. Then I remember that I have had trouble flying out of water with strong currents, and that I would sometimes get pulled back into the water. So before the dark thing got closer, I willed myself to float up and out of the water. It worked, though my feet were still skimming the surface and the dark had come out of the water now, it looked like a man. I turned my head toward the sky and flew away...waking up shortly after. I enjoyed the dream so much that I decided not to move a muscle upon waking, and used the dream re-entry technique (or as I call it, instinct, which is what most "techniques" on this site basically are). I immediately entered a new dream...or wait...was it the same dream. I was back at the friends house, but the flood water was gone. What remained however was an enormous swimming pool, full of crystal clear water. The landscape looked like the american south west, I guess, not having been there. But it was sort of a rocky desert. My sister was relaxing in the pool. Suddenly it was as though we were on vacation. She turned around and gasped...and I did the same...as we looked at one end of the swimming pool we saw that the waters flowed down a very steep slope and into, what appeared to be...a cenote...way down below. A cenote is an underground cave or sinkhole full of water (we went snorkeling in these before in mexico) The sun was shining on the water and rocks down below and suddenly the waters of the caribbean were beckoning me forth and I dove down into the cenote. I think I woke up shortly after. I again tried to reenter the dream, and I believe it worked, but I do not think I was lucid, or I forget what happened. After that I had a few nonlucids. I wish I could remember more. But I do remember how incredibly happy I felt swimming around all night...I love water.
