The trick is to fall asleep quickly. The relaxation part of most WILD techniques is totally unnecessary -- they keep you awake, uncomfortable, and simply not in the state of mind which is required to enter a phase. And a side effect is that they make you ultra-sensitive to external disturbance. I suggest you take a look at the WILD recipe I posted recently. It strips away a lot of the "fat" that exist in traditional methods, and one of the aims is to prevent loss of sleep. I also have a cat and a partner, and they too used to give me lots of trouble. That's not the case anymore -- I can WILD at will, even in very noisy environment such as on an air plane. The truth is -- as long as you can sleep, you can WILD.
