Just like Martin Luther King Jr., most individuals have dreams which consist of imagined scenarios where their lives are exceedingly better than what they currently are. I have had dreams that brought me so much joy, that I was upset when I awaken and realized I had been dreaming. Even now I like to take naps in the afternoon because they are great for relieving stress, and they also help me to escape some of the real things I do not like dealing with, in exchange for a fabrication of the things I like the most.
Someone told me many years ago, "only a dream comes to a dreamer." The adage was used to help me understand that I do not have to fall asleep and imagine scenarios in a dream, but if I stay awake and take action, my dreams can become my reality.
