I think it is difficult to argue that I have had one very specific dream from an early age - unless you count getting to write with Shakespeare and even I have come to realise that this is unlikely to happen now. However, given the focus on dreaming that we all have as one of the defining characteristics of our adolescence, I do believe there is some value in the concept.
It is too simplistic to say 'Oh! I just want to be happy.' Tempting but too simplistic because the concept of happiness is subjective and individual. I also think it too easy to respond with 'I want to be adored', because in all honesty we all want that too; presumably the value of adoration is also tied to the esteem in which we hold the person adoring us. So what is my dream? Or perhaps, what have been my dreams?
