Reflection offers you the opportunity to consider how your personal experiences and observations shape your thinking and your acceptance of new ideas.  Professors often ask students to write reading reflections.  They do this to encourage you to explore your own ideas about a text, to express your opinion rather than summarize the opinions of others.  Reflective writing can help you to improve your analytical skills because it requires you to express what you think, and more significantly, how and why you think that way.  In addition, reflective analysis asks you to acknowledge that your thoughts are shaped by your assumptions and preconceived ideas; in doing so, you can appreciate the ideas of others, notice how their assumptions and preconceived ideas may have shaped their thoughts, and perhaps recognize how your ideas support or oppose what you read.
