This quote means that dreaming can be the only consistent activity in our lives. It is something that is part of us, and it is sometimes the only thing that can make sense of life. Dreaming can be a way to work out our difficult thoughts, imagine what the future might hold, or just a wonderful escape from the reality of life. Having dreams is important because it can be a reminder of hope and give us motivation and ambition for something bigger or better in our lives.
