No, but various people have tried to hypnotize me and been frustrated. It's not for everyone.
Maybe you can get a better one.
Tempted to but doubt if it would work
As far as I understand it is based on how susceptible the participant is to the suggestion, and as I am fairly skeptical on the subject it would be difficult. The hypnotist probably will say what she said to you to everyone as how could they disprove it without a scientific experiment (aside from just knowing they weren't, she probably accidentally hypnotised herself into believing she could lol)
