People often dream when they are asleep, and they are still "dreaming" when they wake up. However, many people are just dreaming, and very few people are dreaming and realizing the scenes in their dreams!
We need dreams, and we also need to complete the scenes in the dreams; we can dream, but we need to complete the things in the dreams in reality; we have to dream often, and we need to be down-to-earth to complete the dreams!
