a dream in reality

A dream is not a wish your heart makes, contrary to a popular Disney song. A dream is the fulfilment of a wish, coming from your mind-your brain. I credit some of this thought to Sigmund Freud, whom I've been reading about. Your subconscious and concious thinks of a goal, or a desire, a.k.a. a dream. Then you think about it and think of how to accomplish it. All in all, listen to your brain, not your heart, because your brain makes decisions and your heart is a blood-pumping organ.
