Sometimes this is what I experience in my lucids:

After get a stable and fully conscious train of thought during a dream, when I try to interact with the environment, my conjurations don't appear as they should. For example, if I want to create a stone wall if front of me for protection against an angry mob, a few things might happen:
1. No wall appears, there no interaction between the mob and the wall
2. A semi-transparent wall does appear, no interaction
3. Semi-transparent wall, mob gets blocked (I'm unsure if the mob can pass through until they reach it)
4. A fully opaque, solid wall is formed, stops mob.

Do you fellows get these power-levels in your dreams?
And would you consider levels 1-3 poorly achieved lucidity?
