As sleepers fall asleep and enter deeper stages of sleep, the brain wave patterns typically progress from alpha waves (associated with relaxed wakefulness) to theta waves (associated with light sleep) and then to delta waves (associated with deep sleep). Therefore, the correct sequence of brain wave patterns is alpha - theta - delta, which is reflected in choice D.
