In which two situations is brainstorming for a paper most useful?
when you’re writing the final draft for submission
when your teacher asks for a list of possible topics
when you’re creating an outline for your paper
when you need to narrow down the scope of a topic

the way you did it is okay (not really the best) but it could use a little work.

explanation:

dreams can say a lot about the personalities,thoughts, feelings, and intentions of people, what exactly do dreams mean? are the dreams we have   a result of our thinking process or are they connected to our hidden desires? facts and fiction will be used to uncover the truth behind our dreams.

quite an interesting way to teach topic sentences, because the answer to this question is the best definition of a topic sentence that one can present, it is as if answering the questions taught you how to do it, this is some real teaching, it is terribly well-done.

the topic sentence in this paragraph is:

topic sentences writers stay on track and keep a paragraph from becoming an aimless collection of sentences about an idea.

which incidentally tells you what a topic sentence should be.
