The 1 to 10 is a good idea. Then it would be like "I had a 8 level lucid dream tonight".. Heh, sounds kinda good!

I think this scale should be only for lucidness, not control.

On the other hand, if there are 2 scales, the control scale (level of control) and the lucidity scale, then you could do it like this I guess:

(LUCIDNESS).(CONTROL)

So, I had a level 10.3 lucid dream tonight. 10 meaning full lucidness and 3 being little control. What do you think? Good idea or bad idea?

Have fun!
