Its been 20 days since i began writing dream journal and doing RC's. I had already 2 LD's in first 2 weeks but it wasnt that much controlable. In my first lucid i spawned dirt bike, i looked in the mirror and changed how i look and i went invisible but it was blurry and lasted very short. I stopped doing RC's and thinking of Lucid dreaming for 7 days now but i can remember dreams from every sleep i go. I didn't write them but now i'm starting again. I got good recall but the thing is i want to improve and do whatever i want in Lucid Dream, is that possible?

Now few questions:

1) When you are more experienced will you be able to see everything the same in dream as if in real world?
2) How long can it take me to control my dreams well?
3) How much can they last?
