Quizplus · Accepted Answer

Jeff's behavior, including walking with a shuffling gait and having a blank expression, strongly suggests somnambulism, or sleepwalking. This condition often occurs during non-REM sleep, and individuals may engage in a range of behaviors during sleepwalking episodes, such as walking, talking, or even driving, without any recollection upon waking up.
