A person who has been taught self-hypnosis may use this exercise daily to reinforce suggestions.
There are no real complications. Hypnosis does not cause anything to happen, but rather makes it easier for the person to achieve specific goals.
When people are relaxed and in a trancelike state, they are more open to suggestion. They can change the way they perceive situations, pain, addiction, or understand behavior more completely. Hypnosis is a tool to help make changes.
