Interesting, thank you! I don't recall that information on the "pinch test" last time I read.

That said, the "look at ground" has never worked for me, and I realized "look at numbers/text" doesn't work for me when I started doing comparison price shopping in my dreams. I'll have to try the breath holding one, but, ahh, given it's a very familiar sensation, I doubt that test will work for me either ^^;
