For some reason it took years for me to realize that WILD is not about what you do in bed, or how still you lie, how hard you try etc. Despite all the instructions about what to do while 'attempting' one, it is 99% about preparation and timing, just like the other methods. When the timing is right, it can happen with minimal effort.
Another turning point was the power of imagination and how little you have to do for your mind to fill in the blanks on its own. For example, when in the right state of mind, you only need to think about something, and your mind can conjure a realistic simulation of it.
