The use of hypnosis in medicine has been established traditionally in health care. Hypnosis, or hypnotherapy, refers to a state of awareness that helps you relax, focus, and concentrate better. In simpler terms, it's a situation in which a person's attention is detached from their immediate environment and absorbed by inner experiences such as feelings and thoughts.

Insomnia is a common sleeping disorder that means "an inability to sleep." However, it is generally used as a term for disturbed sleep, where a person cannot sleep peacefully or gets interrupted by poor-quality sleep.

For centuries, hypnosis has captivated both the public and the scientific community, offering a unique state of heightened susceptibility and focused concentration. As our understanding of this phenomenon has deepened, we've begun to explore its therapeutic potential, particularly in relation to individual differences.
