but to hint and hover , to draw near us in dreams and oracles , or in a waking vision that vanishes as soon as seen , to be dead silent when we question them and then glide back and whisper ( words we can not understand ) in our ears when we most wish to be free of them , and to show to one what they hide from another ; what is all this but cat-and-mouse play , blindman 's buff , and mere jugglery ?
