Answer:
2. The strange thoughts that come when our minds are at rest.
Explanation:
William Shakespeare's "Romeo and Ju li et" revolves around the tragic love story of two lovers who chose death than being separated. The romantic tragedy focuses on how societal and family pressures often became the obstacle for successful love and how detrimental it can be.
In the given passage from Act I scene iv of the story, Mercutio was describing his dream about "Queen Mab" which Romeo declares nonsense. Then, Mercutio declares that dreams are the "children of an idle brain", the result of a 'free' mind with nothing to do. According to him, such dreams came out from nothing and are merely "vain fantasy."
Thus, the correct answer is option 2.
