Most of us know how to daydream, it comes naturally. You might refer to chapter 15 where guided fantasies are used for insight. Perhaps your re-occurring daydreams reveal some frustrated needs that deserve more conscious attention. Otherwise, I'm going to assume you know all you need to know about daydreams and go on to hypnosis. Then they ask you to try to take your hands apart.
Many people find it is somewhat difficult to separate their hands after the suggestion is given.
Other hypnotists will have you stand with your eyes closed, heels together, and imagine swaying backwards. In other words, thinking of some action tends to produce that action if your imagination is vivid enough. For example, make yourself a pendulum out of a small, round object that has some weight to it. A spherical button or glass ornament is ideal, but a medallion or set of keys or heavy ring will do. Then draw a circle on a piece of typing paper and draw two lines intersecting in the middle of the circle.
