Answer:
C. Your muscles are paralyzed so you don't act out your dreams.
Explanation:
<em>Rapid Eye Movement </em>(REM) sleep is one of the most important stages of sleeping, in which the <em>brain is highly activated </em>and can even be noticeable since the eyes tend to move fast, as the name states.
This is the stage in which dreams occur so the <em>muscles are paralyzed </em>to protect the individual from carrying out physical actions.
The body is <em>not relaxed and free to move around</em> and the mind is not cleared of all thought since this is when<em> memory integration occurs. </em>
