There are many variations of WILD.
You can lay still, preferably on your back, untill you feel numb.
Then you start counting. All the way to 100. Visualise every number as you count it. The idea is
that focussing so intently on a conscious effort will allow your mind to stay mostly awake, while
your body falls asleep. Every once in a while stop counting and shift focus to your vision.
If you stay conscious long enough, you may just find the dream has already formed around you.
Another way is to visualise going down a spiral stairway. There are many ways. The important
thing is that it should be a conscious effort that keeps your free will and your rational &
observant self awake, while the rest of you falls asleep.
Remember; The best time to do this is early in the morning, after having slept deeply for about 4 to 5 hours.
Your REM-cycles will start much sooner & be much longer. If you find it difficult to stay conscious during morning-WILDs,
try staying up for a while, do some analytical work (read something, do math, debate on this forum) to awaken your mind somewhat.
Then try going back to bed. If you wake up significantly earlier than you normally do you'll be tired enough to fall back asleep,
yet the brief moment of wakefullness and analytical work makes sure you don't just plumit into deep unconscious sleep.
It's all about balancing sleepiness with wakefullness.
