However, its usage has extended beyond the medical context to describe any situation where someone is made unaware of their surroundings. This idiom can be interpreted figuratively in everyday language as well, suggesting manipulation or control over someone's thoughts, actions, or emotions. It implies exerting influence or power over someone, similar to how anesthesia takes control over a person's consciousness.
