Just last night, I had a lucid dream where I looked for, and found a set of training games. The machine that I used to play the game had a touch screen where I could choose any particular training simulater I wanted (and there were plenty of choices.) I chose a game called "Control" where I had to use TK to play Pinball. It was actually very fun and I got a lot better in TK.

So, the point is, if anyone here is having a problem with dream control, this seems like something worth trying at least once.
