I was given ketamine to reduce my dislocated shoulder. I experienced something very similar to what the author writes, ending up in a black void and feeling like I'm tumbling into nothingness. I remember yelling out in the ER "no, no, NO!" as the spinning and tumbling toward the void increased. I believe recreational uses refer to this as the "k-hole" and I found it extremely unpleasant.
