Dream can also refer to an aspiration or a desire. But personally, I don't like that use as much, not because I don't think you should have aspirations and desires, but because when you call them dreams, that's what they become. Ethereal and fleeing. Insubstantial and out of this world. Untouched and out of reach, leaving you forever star-crossed and broken hearted. So don't make your aspirations into dreams. Give them weight and substance so they don't fly off without you. Make them your wings and let them lift you. Make them a reality.
