When he came back to play again, he looked nervously at the top of the piano, but there was nothing to be seen. He sat down, and bent over the keyboard, and his hands began to run to and fro softly. When he looked up he saw what he was playing as clearly as he could have seen the notes if they had been there: but the wavy line was upright now, and drifted upwards swiftly, vanishing at a certain point; it swayed to and fro like a snake beating time to the music of the snake-charmer; and he looked at it as if it understood him, and nodded his head to it, to show that he understood. By this time it seemed to him quite natural, and he forgot that there had ever been a time when he had not seen the music like that. On his way home after the concert, it occurred to him that something unusual had happened, but he could not remember what it was. He dined by himself, and after dinner went out into the streets, and walked in the midst of people, as he liked to do, that he might take hold of something real. But he could not concentrate his mind, he seemed somehow to be slipping away from himself, dissolving into an uneasy vacancy. The people did not seem, very real that night: he stopped for a long time at the corner of the pavement, near Piccadilly Circus, and tried to see what was going on around him. It was quite useless. The confusing lights, the crush and hurry of figures wrapped in dark clothes, the noise of the horses' hoofs striking the stones, the shouts of omnibus-conductors and newsboys, all the surge and struggle of horrible exterior forces, seeming to be tightened up into an inextricable disorder, but pushing out with a hundred arms this way and that, making some sort of headway against the opposition of things, brought over him a complete bewilderment. 'I can see no reason,' he said to himself, 'why I am here rather than there, why these atoms which know one another so little, or have lost some recognition of themselves, should coalesce in this particular body, standing still where all is in movement.' He looked at the horses pulled back roughly at a cross-current, and tossing back their heads as the hind-legs grew convulsively rigid, and he felt sorry for them, and wondered why the driver was driving them and why they were not driving the driver. Some one ran violently against him, and apologised. The shock did nothing to wake him up; he noticed it, waited for the effect, and was surprised that no effect came. 'Decidedly,' he said to himself, 'I am losing my sense of material things, for, slight as it always has been, I have always resented being pushed into the mud.'
