A hypnosis classic

"Kim, I want you to imagine something. A barnyard. There are cows grazing, pigs rolling in the mud, horses happily running the fields, sheep bleating in their pens, but you don't see one animal you expect. What is it, Kim?"

"A chicken," Kim droned.

"Yes, and the reason you don't see a chicken is because you're the chicken. You're looking out from your own enclosure. A dumb, clumsy, noisy, clucking chicken. Let that idea slowly fill your mind. And when you are ready to fully let go and become that chicken, give me the best cluck you can."

"Okay Kim, wake up as the chicken in 3...2...1...now!"
