suehypno:

I remember first learning about this in one of the first books I read about hypnosis, and it was probably when I really became fascinated by the concept and appearance.

I’m curious what everyone’s experience is with this, and whether you think this still hold up as an accurate or useful guide to suggestibility. I’ve seen some somnambulists absolutely exhibit the full roll-back with ease while others struggle with even the up-gaze.
