Self-hypnosis is a process where an individual uses relaxation techniques and focused attention to enter a state of heightened awareness, often referred to as a trance. This state allows the person to access their subconscious mind, making it easier to change behaviors, reduce stress, or manage pain. During self-hypnosis, individuals may use suggestions or visualizations to achieve their goals, such as improving sleep or enhancing performance. It is a safe practice that can be learned through various methods, including books, audio recordings, or guided sessions with a trained professional in hypnotherapy.
