A method to induce an immediate psychosomatic change in a patient optimal for a particular medical procedure, is provided. The method uses a brain-computer interface integrating a loop of biofeedback and neurofeedback components, interactive, immersive, 3D virtual reality (VR) modules utilizing hypnotic or guided-response, learning, placebo and experience-ratification principles. The method will differentiate between low and high hypnotizable patients as well their specific abilities and limitations by their distinct brain patterns and will deliver VR output content appropriate for the current and targeted psychosomatic state of the patient, needs, and stage of a particular medical procedure thus being applicable to any medical patient regardless of abilities. The device will continuously measure the patient's physiological markers and will customize the intensity, order, timing, and content of the output “dose.” The method is designed to be quickly implemented, entertaining and minimally obtrusive to distressed medical patients and medical settings.
