My take on this song is that it's about someones' personal expectations on what they can and can't achieve in life, wishing they could achieve more than they feel they realistically could, hence 'can't we all dream'. The repetition of can't we all dream suggests to me that desperate attempt to realise what seems impossible to us( those unattainable 'dreams') and the lines about 'sailing to the moon' relate to how ridiculous all our dreams seem in those moments when we accept defeat and realise how stupid it was to dream of such unrealistic things.
