Although Hypnos is the god of sleep, against the commonsense notion, hypnosis is not related to a sleep phase. On the contrary it's a natural and spontaneous waking state with increased concentration, hypervigilance that allows better collaboration between consciousness and unconsciousness to let unsuspected resources emerge. In reality, everyone does hypnosis spontaneously every day in order to regenerate the brain.
Hypnotherapy is used against various ailments like stress, insomnia, phobias, allergies, migraines, tobacco use, addictions, various chronic pain, bulimia nervosa, psychosomatic disorders and anxiety disorders. It’s also used to prepare for a surgery, an exam, a childbirth, a sporting event as well as traumas and grieving. It is a technique that is practiced alone or in conjunction with psychotherapy, depending on the problem, the target and what the therapist recommends.
Do hypnosis with a specific purpose reports to an apprenticeship, a progressive experimentation of logging with oneself. Therefore, assuming that we can all learn, we're all hypnotizable. The only restrictions might concern patients with a personality structure too dissociated or acute psychosis.
It is known that in psychotherapy, a change is only efficient and durable as long as there is a synchrony between the body, the intellect and the effects. Sometimes the conscious and rational part of our brain suppresses overemotional contents posing a threat to the steady- state one has created. This steady-state although sometimes unsatisfying is often reassuring because well known. The idea behind hypnosis is to create a bridge between the two cerebral hemispheres to stimulate the intuitive parts and to promote healing through the uncovering of creative resources bypassed by intellectualization.
