First of all, thanks to Ev, that finger through your palm thing works like a charm, and thanks to everyone else for your tips.
Yesterday I had a real lucid dream. Up to then I had just had low lucidity dreams and some even lower than that. I mean I knew I was dreaming, but I would go along with the surroundings. Well it started out like a normal dream, I was at my friends fiancee's place listening to music and building a train set. Out of the blue I was in that train set and it was traveling around and some rats were gonna try to eat me. Then the dream changed again, and I was Plucky from the Tiny Toons getting chased by an old witch that was trying to cook me. So I got away and turned into myself again, I was walking around when suddenly that witch showed up again and she was trying to make me into a duck again. This is where I began wondering about the dream so I did the palm through finger test and it worked!!! I began to fight this witch, she was telling me how lucid dreaming is a tool of the devil, and now that I was lucid, I was going to hell. Anyways, I started doing things I had never done in a lucid dream before. I was fighting with her flying (flying I had done) but also pushing her around the whole room like a ragdoll by just sticking out my hand, without even touching her. So I finally got out of there and a cousin of mine and I we threw down Peru's government single-handedly.
So another of my cousins joined us and now we where in Houston, they wanted to take a cab, but I said wait, look over there... and just by extending out my arm and sticking out my hand again, I made 3 cars appear, a Lambourghini, a weird hybrid of a Mustang-Camaro-Dodge, and a Corvette. One of my cousins called the Lambourghini... bastard, and the other the Dodge lookin' thing, it was standard, he doesn't know standard so I said just look away, I did too, pointed my extended palm at the gears and presto, it had become an automatic. We only drove a little bit, then I woke up.
Sorry for making this so long, but I had to tell somebody.
