According to the World Hypnotism Day Official Site,
World Hypnotism Day, January 4th, was established to help educate the general public of the truth and benefits the timeless and natural process of hypnotism has to offer anyone. Movies and books of fiction have warped the perception of hypnosis, which is why World Hypnotism Day is a necessity in order for more people to understand the truth and use this natural, expedient and effective process for personal change.
I don’t know much about hypnotism as a method of changing anyone’s life but I do remember this funny show I saw in college when a hypnotist came to do a show. He had people taking off their clothes because they were too “hot” (not all of their clothes but one person did go a little farther than I think he intended! One guy was clucking like a chicken! It was a great show and this special day made me think of the memory!
