After general anesthesia there is a possibility of dreaming. General anesthesia drugs contain sedative hypnotic drugs, can inhibit the human body’s brain nerve center, so that people will not feel pain during the operation, but also induces the human body to enter a state of deep sleep, so there will be the possibility of dreaming. Some studies have shown that dreams after anesthesia may be related to the depth of anesthesia, if the degree of anesthesia is deeper, the shallower the memory of the dream, and may even have no impression of the dream. Dreaming during general anesthesia is a common phenomenon and may vary from person to person; this usually has no effect on the surgery or postoperative recovery. If any serious discomfort occurs after anesthesia, it must be handled promptly by a medical professional.
