I like it. I already classify mine as either high-level LD or low-level (2 being low-level and 3 being high-level). It has a few flaws though:

As for 4 and 5, they are pointless to describe the level of lucidity, as I've had VERY realistic lds with no supernatural control. though maybe the awareness of your body could be factored in.

1 kinda never happens.. i'd merge it with 2.
