I tried doing this last night and it worked - sorta.
I haven't been able to even remember dreams for about 3 years now, but last night I remembered 4! Although whilst having these I didn't know that I was dreaming, yet alone have any control, but one of the dreams felt so real. I was in the car with my brother who's learning to drive atm and he was driving. This was illegal as we had no L plates and also i haven't held a license for 3 years yet (so can't teach him to drive), anyway, the police suddenly appear behind us and start flashing the lights for us to pull over, but instead of pulling over i grabbed the stearing wheel and attached it to the passengers side of the car with ease! The thing that made this dream vivid was that i could really feel the muscles in my arms turning the wheel (due to it not having power steering) Anyway i continued to drive on a tad and pulled over and then realised that i shouldn't have been able to just attach a stearing wheel! So i tried to put it back on the drivers side but it would't click into place, then i fell out the door and woke up.
It may sound like nothing but to me this is quite a big thing! I think with practice i might learn to Lucid dream pretty soon, and gets some clark kents skills on the go!
