We make broad wishes as children. As we age, what is possible constantly shifts. Asking an adult to make a wish, they would lean towards practically, maybe for a better home, a better job or financial freedom. Their wishes are not as broad or unlimitless like a child's would be.
Perhaps child like tendencies would slip out, wishing to be a billionaire or being a super star, but they wish based on educated possibilities, limiting what could be attainable in their minds.
That piece has the mind in a dream state, but it's fragmented, shifting, rotating elements. If we were limitless, what could we do? What would we wish for?
