I had a lucid dream yesterday where I was in my old hometown. I was on foot but really didn't want to walk.

So I tried to summon a Pagini Zonda (I'd been watching Top Gear previously).

I tried everything but the Zonda wouldn't come! I made elaborate hand gestures closed my eyes and opened them expectantly, and even tried exotic and ancient chants.

Nothing worked. Summoning a car would probably have been easier, but how do you summon specific things like a Zonda? Is there any training I can do, whilst lucid?
