Train? Yes. Hypnotize? No.
Humans are the only species that can make use of what Michael Ellner has referred to as "the transformational magic" of an provides both the opportunity and the occasion for those who have the ability to use their imagination in an "Alice-in-Wonderland" fashion to go ahead and do so. If we choose to adopt Michael Yapko's view that all communication is hypnosis, then "birds do it," and "bees do it." My own preference, however, is to use a more conservative definition such as Michael's, and "let sleeping dogs lie."
