Yes, but when you are lucid you control the percieving aspect of the cycle, and therefore indirectly control the creation aspect of the cycle. When you're lucid, and want to summon say, an airsoft gun, you expect to see an airsoft gun appear, and then your SC turns this expectation into reality. I think most problems with dream control occur when the dreamer is not confident in his/her ability to do whatever their trying to do, and so the SC takes the uncertainty of the outcome and may make that occur instead of what the dreamer originally wanted. So if you are thinking, "an airsoft gun will appear before me" but at the same time in the back of your head you're unsure if that will really happen, theres a good chance that your SC will cause the intended outcome to not happen.

I didn't completely understand your question, so I hope I gave you the answer you were looking for
