Hypnotically implanted assistances in keeping yourself safe from, irl things happening while trancing, malicious hypnotist, unintended limit crossing, accidental triggering, and undesired programming or triggers. Response to unexpected irl interruptions while under hypnosis or post hypnotic effects is waking up and them being undone. Same with malicious attempts to cross limits. To focus and give a warning if it seems like the hypnotist is simply making a mistake. These safeties are meant to be general and vague. They are just meant to help your natural desire to stay within your own limits is protected, encouraged, and given a more tangible shape and direction. That direction often being straight back up to awake.
