Last night, I had another LD, but how I became lucid is the most interesting.

For some reason, when my dream started, I remember that my field of view was rippling, like water. It prompted me to do a RC, which worked. This is the first time I ever remember anything like this happening.

Has this ever happened to anyone else before? Is this normal? Is this good, bad? It was really cool, and led me to one of my best LDs.
