Restless Legs Syndrome (RLS) is a neurologic sensorimotor disorder that is characterized by an overwhelming urge to move the legs when they are at rest. The urge to move the legs is usually, but not always, accompanied by unpleasant sensations. It is less common but possible to have RLS symptoms in the arms, face, torso, and genital region. RLS symptoms occur during inactivity and they are temporarily relieved by movement or pressure.
Nightmares are dreams with vivid and disturbing content. They are most common in children during REM sleep, but they can happen to adults as well. They usually involve and immediate awakening and good recall of the dream.
