Final answer:
REM sleep behavior disorder is marked by physical activity during REM sleep such as kicking and punching, as a result of the body's failure to undergo muscle paralysis. It leads to disrupted sleep and potential injury without memory of the actions.
Step-by-step explanation:
The symptoms associated with REM sleep behavior disorder (RBD) are quite different from the options provided in the question. RBD is characterized by the lack of muscle paralysis that normally occurs during REM sleep, leading to high levels of physical activity during REM sleep, often associated with disturbing dreams. This can include kicking, punching, scratching, yelling, and other behaviors as if reacting to a fright or attack. People with RBD can injure themselves or their partners during sleep with these behaviors, disrupting sleep without memory of these actions afterwards.
