Yes, I think the third level was a medium of escape for Charley. He had a strange day–dream wish to escape from his present worries. He wanted to escape into the past. He believed that in the old days, life was peaceful. People in his grandfather’s time lived a carefree life. All those charms were lost. The present day world is full of worries, wars, tension and haste. Charley was always lost in his own thoughts. He was unaware of his surroundings. One day he found himself in the lobby of the Roosevelt Hotel and some other time he came up in an office building. Another day, he reached the third level.
