Oh I totally get the hard and not painful part, I used to fall 50 meters onto a concrete all the time in my lucids. Everything made out of bricks, that must've been bizarre, like a texture glitch in a videogame . I too congratulate you on such brilliant execution of dream warping, so cool.
I've had stuff like the goggles happen with me, especially since I sleep with a sleep mask. I once spent like 30 seconds just pulling off sleep mask after sleep mask, until I finally just decided to use heat vision to burn it off of me. Congrats on the lucids. I would say you could also count the brick changing as Advanced Object Changing (10 pts), and the light/dark changing as unspecified dream control (5 pts).
Yes, the majority of my lucid dreams are people free, I think. Weird, indeed.
