Why doesn't technology work properly in dreams?

It’s well known that mechanical and electronic stuff typically doesn’t function as it’s supposed to in dreams. Lucid dreamers use this fact to test whether or not they’re dreaming: if you try to flip a light switch in a dream, chances are it won’t have the expected result. Clocks don’t work properly. Last night in my dream I tried for many minutes to get to the “contacts” menu on my cell phone, and never could. Yet these are all things that we’re very familiar with.

The brain can spin incredibly rich, detailed simulations of reality, so why can’t it make the light switch work? Is technology such a new feature of human life that we don’t yet have the neural tools to dream it?
