The trick in hypnosis is that there is no trick. It is just a deep state of relaxation, and a willingness to hand over control to someone else. If it isn't up to you to decide what the obstacles are, you are more likely to do things without even trying. More likely to do or not do. More let's see exploration than I can't predetermination. I am a 'Try Hard'. If someone says 'You can't lift your hand', I find it incredibly difficult not to challenge them and test if I can. Of course, I can lift my hand. That isn't the point. If I challenge on that first point, I don't get to go on the journey. Fiction can go further than fact because it isn't constrained by our understanding of each step.
