I was divving in the ocean and there was a huge coral reef underneath me, but quite deep, more than 10m down. Interestingly there was some sort of ladder or pier. It would have been great for scuba diving but I had nothing with me, not even goggles and a snorkel. That sucked, I really wanted to dive down there but even in a dream it didn't work with out proper equipment. Somehow I still could see the underwater world clearly even eithout goggles, it was realy vivid and colorful, especially the blue. But I hist couldn't get down there.
