That was a long post.. But I read it all Interesting method but I don't understand what made you stop. Was it when you imagined this lucidity trigger (Dream?) object getting crushed and suddenly you just can't get lucid? Can't you just try to recreate that object again?
I am sorry if I am totally off but I don't understand how that object helepd you attain lucidity in the first place o. O

You seem to be much more experienced when it comes to induce wake initiated lucid dreams than me, but maybe this advice can help anyway.

Have you heard about the DEILD method? You basically wake up from sleep and then re-enter the dream again, and for you I imagine it would be very easy, because you can just use the buzzing sound as a tool to enter the dream. So you wake up, then listen for that buzzing sound or even inducing it yourself (because based on your description it sounds like you can do that!) and then just do your thing and that should be enough to enter a dream, crushed lucidity object or not

As for dream control and different awareness etc. I suggest that you watch Reece Jones "Five Layers of Lucidity" to easier keep track of where you're at and what you can do about it. I use his Layers for the same purpose in my Dream Journal and it have helped me a great deal.

Good luck!
