Metaphor For Hypnosis

I think a good metaphor for hypnosis would be:

Our mind is like a big patch of grasses.

Everytime when a thought flashes in our mind and/or we experience something (like watching a movie, reading a book etc) we cut away some grasses. The deeper the thoughts and/or experience, the more the grasses can be easily uprooted. Through our day-in and day-out thoughts and experience, we eventually create a trail of path that makes our "travelling in our mind" to the desired destination much more easily. For example, you have a deep desire to smoke, for each cigarette you put into your mouth, you cut away the grasses or even uproot them. Through your repetition, you will in no time create a path that makes you want to smoke effortless.

The job of a hypnotist is to help you plant back the grasses so that once the blazed trail is covered up again, you no longer can have the desire to get back to smoking because your brain can't find the path to help you reach the destination. This is done with every input of positive suggestions into your subconscious that readily create another pathway. This time, it will be no longer the old negative pathway but a new empowered pathway.
