Yes, if they want to be. It is an effective process that has been proven to work well. In fact you will have been in hypnosis many times already.
Have you ever 'zoned out' watching TV, reading a book, doing the dishes or driving a familiar route home from work? If so chances are you were in hypnosis. It is a natural state that everyone goes into multiple times a day without realising. It is also the state you wake up in and fall asleep in.
