Abstract: A hypnotherapy system includes wearable element and non-wearable elements, delivers instructions and media segments, measures state or activity of a subject and provides post hypnotic re-enforcement stimuli to the subject. The system includes a storage unit storing personalized session scripts for hypnotherapy sessions for the subject, where a hypnotherapy session includes dedicated media-based treatment processes to control different stages of hypnosis and follow up posthypnotic re-enforcement suggestions. The system includes a script handler to run the session scripts from the storage unit for a hypnotherapy session selected by the subject, allows the session scripts to be synchronized to different sleep stages and updates the session scripts according to an analysis of readings of the wearable element and non-wearable elements.
