Oh Hypno, how I despise that picture It really is inaccurate and unfortunately it shows up all over the place. As Ashikael mentioned, you would want to do that on a WBTB, at least, and forget all the junk about sleep paralysis, the weight on your chest, and not moving. I would check out Sageous's WILD class if you are interested in WILD, or the tutorial by Mzzkc.
