““All at once, with the speed of lightning, a sudden question, never thought of before, shot across my mind. I stood stockstill in the middle of the road confronted within to the depths of my being with the insistent inquiry, "What am I?', coupled with the pressing interrogation from every object without, 'What does all this mean?' My whole being as well as the world around appeared to have assumed the aspect of an everlasting inquiry, an insistent, unanswerable interrogation, which struct me dumb and helpless, groping for a reply with all my strength until my head swam and the surrounding objects began to whirl and dance around me.””
