In this depth test performed by hypnotist, a subject is asked to close and relax their eyelids.  Then, the subjects asked repetitively to imagine their eyelids becoming so relax and comfortably heavy, that even if they want to open them, their eyelids are indeed too heavy to open. Once this is achieved, the subject will be asked to try and open their eyelids, and finds that their eyelids are indeed too heavy and relaxed to open. Lastly, the hypnotist will suggest that the subjects eyelids return back to normal, in which their eyelids easily open as they naturally would.
