I think this is a great idea. One of those things that is so obvious once I see it, that I am kicking myself for not thinking of it on my own. Taking into account the proposition that the subconscious communicates in a completely non-straightforward english method, I have a plan for my next LD:

Step 1: Stabilize it by rubbing my hands together or something
Step 2: Openly ask my subconscious in general to show me the most effective method for communicating with it in order to receive definite, clear responses that can be communicated with others in waking life.
Step 3: Use whatever method that is to ask my subconscious to reveal itself to me, in particular, what I need to know to have more lucid dreams.

Sounds like a solid plan to me. Unfortunately, my track record for lucid dreams is on the order of 12 per year, often all in groups of 3 or 4 at a time, so it may be a while before I report back. But the good news is that they do in fact happen, and it's only a matter of time :-)

If anyone has any ideas or tweaks to this plan, a better plan, or another idea, let us know.
