Answer:
A. It shows how new and influential ideas can come across from dreams.
Explanation:
Ben Slivnick's "The Story Behind Your Dreams" argues about the origin and causes of why people dream. Are dreams a vision or mere memories that our subconscious mind plays in our thoughts?
Arguing on how many theorists believe in the importance of one's dreams and how they are connected with one's memories, Slivnick delves into how dreams are an essential part of our lives. He presents an example of how Paul McCartney and Rene Descartes are some famous people who have got inspirations or were influenced by what they saw in their dreams. And by taking these personas as examples, the author presents how dreams can help influence a person in developing new ideas.
Thus, the correct answer is option A.
