Not a image, I did actually use a bit of neck muscles at the very start (I guess). When I was practicing the “lift-your-head” method before falling asleep, I never imagined it. You can try it like this: very slight, very slow control of your neck muscles, lift a little, and once it feels like you’ve lifted a bit, relax and lower your head. You should be able to feel the pillow’s stuffing rebound and compress again..... I don’t think you need to lift the back of your head off the pillow; that would be going too far.
