You don’t have to think about the mechanics, of what hypnosis is, in order for you to experience a hypnotic trance. In a similar way that you don’t have to think each night about the mechanics of sleep in order to achieve a good night’s rest.

But, just thinking about relaxing.

Hypnosis is simply focusing the mind so that you can use your mind more effectively.

Hypnosis is also completely natural.

A hypnotic trance is only possible with the full co-operation of the individual.  And no individual can be hypnotized against their will or without their full co-operation.  It is impossible to hypnotize anyone who is subconsciously unwilling to be hypnotized.

The individual is always in control and if they decide for whatever reason to end their session they are free to simply open their eyes. Equally their on-going hypnotic trance relies on their continued co-operation. Should they decide not to continue with the trance. Or not to accept any particular suggestion they cannot be made to.
