In my first LD I was flying over an ocean. At first it looked sparkly and beautiful, and as I got lower over it, big waves splashed up all around me -- very detailed. However, as I continued, it looked to be tiled, like a bitmap texture in a video game. It was the same square of blue water repeated over and over again, into infinity. I found that to be somewhat disturbing and boring. I'm not sure why sometimes there is more detail and sometimes less. I normally hear sounds and music in dreams very clearly -- never any lack of depth or clarity there.
