This is really just a lo-fi starter dream...as you go deep below the surface of the sea. More will come from this dream in the future.
This was an obvious second experiment after the Tree dream. One image at the top creates the effect of the water's surface and light rays. An additional image is used for each school of fish, which are then manipulated by opacity, size, and position. I began to play with additional images, including an emerging submarine (schematic, of course), but gave up on that for now. jQuery to CSS3 transition support is provied by the excellent jQuery Transit plugin.
