I'm not much of a WilDer, But when I do it I just relax and focus on not thinking words. I just wait until sounds and images start to enter my mind on there own.

Even when you dream about mundane things there should be something about your dreams that are different from everyday life.

Anyway, whats really important is to get yourself to think about whether or not your dreaming while in a dream. You don't always have to notice something odd for that to happen. You just have to question whether or not your dreaming enough when your awake. So that you will eventually do it while your sleeping.

Sometimes you will just become Lucid spontaneously.
