I think the American Dream says that anything can happen if you work hard enough at it and are persistent and have some ability. The sky is the limit to what you can build and what can happen to you and your family.
I had daydreams and fantasies when I was growing up. I always wanted to live in a log cabin at the foot of a mountain. I would ride my horse to town and pick up provisions. Then return to the cabin with a big open fire a record player and peace.
