A 56-year-old man comes to his physician, accompanied by his partner, for evaluation of “abnormal movements that occur while he sleeps.” Symptoms began around four months ago. According to the partner, the patient has on multiple occasions exhibited various movements, such as throwing a ball or punching invisible objects, while asleep. The partner has been sleeping in the guest bedroom for the past several weeks to avoid getting hurt by him. The patient is unaware of these activities, but he recalls vivid dreams of playing baseball and fighting off home invaders. Past medical history is noncontributory.
