No. In fact, you have probably seen someone during a stage show who simply didn't react to some skit, so the hypnotist moved on to others. That person might not have felt like doing what was suggested, might have objected to the content or might simply have been feeling really good at the moment and chose to ignore the hypnotist.
What you see during a stage show is a group of people playing "make-believe" with an intensity that you would not understand unless you had experienced it. If you have seen children playing and seen the intensity with which they can visualize the environment and components of what they are doing, you might realize it's been a while since you have imagined something that vividly.
As adults, we forget how much fun it was to imagine that the ground beneath the monkey bars is "lava" and to do so with such intensity that there's no way we are going to be the first to drop. The people on stage have rediscovered how much imagination and play can be.
"Occam's Razor" states that the simplest explanation is the most likely.
Which is most likely?
Yeah, it is. Try it some time. Those folks are playing the most vivid and real game of "make believe" of their entire adult lives. Not since being children on the playground has imagination been so real.
It's fun, refreshing and it feels really good. Why isn't everybody doing this?
Stage hypnosis can encompass several types of performances.
The most obvious is probably the stage shows you see at the fair, in a club, at a corporate event or even at a graduation party. The hypnotist tests the suggestibility of the audience members, then brings those who most likely to put on a good show up onto the stage. From there the comedy begins, with routines that demonstrate hypnotic phenomenon in a humorous way. At it's best it's hilarious, fresh and a fun experience for all. At it's worst, it's demeaning, predictable, not funny and even dangerous.
Another type of stage hypnosis is the hypnosis demonstration. In this type of performance, the purpose is to educate, rather than to entertain. Hypnotic phenomenon takes front stage and the comedy takes a back seat. In this type of show, the purpose is for you to walk out with a better understanding of what hypnosis is and more importantly, what it is not.
The final category is the seminar presentation. The purpose of this type of performance is once again educational, but in this case, hypnosis is only used to prove a point about some other topic. A classic example is a performance given before a group of salespeople, where hypnosis is used to show illustrate how a mindset can have a large impact on the success or failure of a sale.
