I was in some type of 'park'/carneval which seemed underwater but it had all the games, and activities associated with it. I think I was one of the ones running it. And I had to rise to the surface to breath every so often. But I felt like I was flying the whole time. Then I became involved in an activity which was to take me above the surface and let me fly. Which I did and I felt so free. One of the people who I remember being there was a guy I knew in highschool and my mother and children. There were people all over and they were all basically happy and having fun. I could walk and talk in the 'park' and it wasn't like I was drowning, but like I lived in that atmosphere.
Water usually represents your spiritual self, your emotions or your soul sometimes. It could be that your dreams are showing you that exploring this part of you will be a fun thing to do, making you feel free and happy. Or it could be that you already know that and you were simply enjoying yourself in the dream in the best way you know how.
