People who develop delirium may act abnormally and feel more drowsy or sleepy than usual. They have trouble focusing or are easily distracted. They may ask you to repeat what you said multiple times or appear not to have heard you. Sometimes in delirium, people may not remember the date, time, where they are or why they are in that location. They may recall memories from the past or appear to see or hear things that are not present. They may not recognize familiar faces and be agitated and restless.
