A person who has had dissociative anesthesia usually does not remember the procedure, especially if a sedative has been given along with the pain medication. Most people feel back to normal within a few hours. As the medication wears off, an individual may have intense dreams and even hallucinations. If the procedure corrects the problem and a hospital stay is not needed, the person can go home. Someone else must drive the person home, because the medications can impair coordination and reflexes for several hours.
