I am a mutt, the Italian is the easiest to see.
There is also Irish, Russian and Hungarian.
I like the idea of a sacred spot in your mind and i know what you mean when people say they can see you 'check out.' I used this trick when i was at the dentist having my wisdom teeth recently pulled. I 'checked out' and went to one of my favorite trails in the Grand Canyon. Unfortunately i seem to have scared my nurse, as she got weirded out, shook me, and asked if i was okay.
I said, "i'm fine; I'm hiking in the Grand Canyon."
Has she not seen that before? I am sure people do this kind of thing all the time to go away from physical pain.
Do you know how people know? How does your face change? Do you get pale, or do your features go slack...or something else? I'd like to know what the nurse thought she saw when she was unnerved by me.
