The short answer is no.
Any qualified hypnotherapist will conclude by counting you out of the hypnotic state several times and encouraging you to stay in the office for a minute or so afterward to make sure you're fully alert and aware. Even if that somehow doesn't happen, you can always count yourself up by saying "One, two, three, four, five -- eyes open, wide awake." In fact, if you're having a day when you're feeling especially distracted by one thing while wanting to focus on something else, speaking that phrase aloud is remarkably effective.
We all have days like that. According to Marc Gravelle of the Hypnosis Motivation Institute, we can sometimes experience a condition called "waking hypnosis," which he describes as "increased suggestibility to environmental factors." He alludes to people being in such a state when they fall in love.
"Certainly the condition of being in love is a supremely strong emotion. So intense it can be overwhelming (or overloading). Even though it is a positive experience, the persons in this emotional state become intensely 'suggestible' to each other, sometimes finding themselves doing things they otherwise would have never considered. This super-suggestibility is the same as hypersuggestibility."
It doesn't occur to us to question whether we're stuck in hypnosis when we're in love. But we might think so if the distractions are brought on by depression, chronic pain or other physical discomfort, or stress or anxiety. We may find ourselves misplacing things, losing track of time or feeling we simply can't make a decision.
Gravelle advises, "The simplest immediate solution is to do some concentrated stretching of various muscle groups. Stretching always assists greater conscious presence awareness, or exiting hypnosis." If you follow the stretching with the counting out technique mentioned above, you'll immediately feel more alert, aware, and ready to go about your day.
