I have had about 4 lucid dreams total. Last night I had one and decided to fly. And I flew, just like that. Although I did have a bit of a hard time slowing down and landing where I wanted because of the inertia you know.
I tried changing a car to a ferrari by looking away and looking at it. It changed shape, but never into a ferrari though.
I don't think that's too bad for a newbie!
