I agree with everyone above. Lucidology and Nick Newport is really really unreliable information. To WILD you essentially need to be in the same comfortable state as when you normally fall asleep. Before I fall asleep--like most people--I roll over a few times, drift in and out of consciousness, and don't even notice the shift when I lose consciousness. The point of a WILD is to hang on to consciousness by just a thread; with guides like Lucidology it pretty much contradicts itself, if you're laying still and get all these distracting uncomfortable urges or "signals" then it's going to be impossible for you to remain comfortable enough to go to sleep.
