Yes, your dream needs to be big. It needs to be something that is seemingly beyond your capabilities. But it also must be believable. You must be able to say that if certain things take place, if others help, if you work hard enough, though it is a big dream, it can still be done. Good example: A person with no college education can dream that he will build a $50 million-a-year company. That is big, but believable. Bad example: That a 90-year-old woman with arthritis will someday run a marathon in under three hours. It is big all right, but also impossible. She should instead focus on building a $50 million-a-year business! And she better get a move on!
