Dreams are where possibility shades into actuality. They’re how the world builds and sustains itself. Realism is false because realists never make anything new or exciting. Without dreamers, the unknown and unthought-of engulfs and destroys reality.
When people tell you to be realistic, tell them to dream. Dreams are made of love, made of passion, made of the infinite vitality that constitutes life. It is our essence and quintessence.
