Floating Above the Clouds: An Ethereal Swimming Experience

A person swims in a crystal-clear body of water high above the clouds, with a bright sun or moon directly overhead. Fluffy white clouds surround the swimmer, giving the impression of floating in the sky. The water is calm and reflective. The overall mood is serene and dreamlike. Focus on the surreal juxtaposition of water and sky, and the sense of freedom and tranquility. The style should be photorealistic and emphasize the bright, ethereal lighting.
