It's because the young girl dreams of being a handsome superhero. She dreams of flying and the mother even says "Oh, if only I could fly", both of which indicate very powerful situations. Also, I feel like as a little girl the character is often left out, like when her parents are talking in the morning and she can't get up until her mom comes wake. But the girl mentions in her dreams that she can see everything that is happening, perhaps because she is now a woman and not left out like she is in her real life. Finally, she dreams of being a superhero with superpowers, this shows that she wants to be powerful, but cannot be in her waking life. I believe the vision that writer Judith Ortiz Cofer is trying to portray is that women want to be powerful. The daughter and mother want to fly and do something more with their lives, but they can't. I believe many women could relate to the story when it was written in the mid-20th century. Indeed, at the time, women were expected to be housewives and not do many extraordinary things. Additionally, I believe many women wanted to do powerful things, like vote and get a job, and it was a time when the view of women's roles was different.
