I wonder if anyone also tried
it's happen to me one time,I mean I try it one time. around 2 years ago. during the dream I found a wallet, ( wallet or money are my "signs" ,some kind of "awareness" in the dream, telling me things are not real here)
So I try create something, I manage to remove 2 people form the dream, create a huge castle,and second castle next to it(mirror image). each time I was doing something ,I feel I'm going to wake up soon. I also manage to fly over the 2 castles,but i wake up after it.
