Hypnotic language within treatment
Hypnosis can be seen as the power of suggestion with a more intense result. Suggestion, or subliminal messaging, is powerful enough that it is used in everyday advertising and even often in shopping centers to encourage people to spend money on certain items. It is so effective that it has actually been regulated so that free will is still an option when shopping or watching TV.
Taking suggestion to the next level is typically called hypnosis. Those who take a scientific approach explain that a hypnotic state is one where the pathways in the brain that control behavior are not concrete and therefore are able to be accessed by a skilled practitioner by simply bypassing the critical faculty and talking directly to the subconscious mind. Those who take a spiritual approach explain that by allowing the subconscious to interact with the practitioner, behaviors and even experiences can be changed.
Putting someone into a hypnotic state can help improve memory of specific events, can help modify behaviors, and can help someone change their associations. Those who use is as a therapy for depression are often hypnotized in order to change their basic associations. For instance if a victim of abuse is depressed because they associate lollipops with childhood pain the association they make with the lollipop can be changed. When they continue to see lollipops they can start to associate them with good memories instead of bad ones.
