Confusional arousal (or "sleep drunkenness") is a parasomnia where a person partially wakes from deep sleep but is disoriented, confused, and acts strangely, often mumbling, crying, or thrashing, without being fully awake or aware of their surroundings, usually with no memory of the event later. It's common in young children, often triggered by sleep loss, fever, or travel, and typically resolves as they grow, but it can affect adults too, sometimes linked to other sleep disorders or medications.
