A high price for living too long with a single dream

From The Great Gatsby, overall better observed but shallower than I remembered:

No telephone message [from Daisy] arrived but the butler went without his sleep and waited for it until four o’clock—until long after there was any one to give it to if it came. I have an idea that Gatsby himself didn’t believe it would come and perhaps he no longer cared. If that was true he must have felt that he had lost the old warm world, paid a high price for living too long with a single dream. He must have looked up at an unfamiliar sky through frightening leaves and shivered as he found what a grotesque thing a rose is and how raw the sunlight was upon the scarcely created grass. A new world, material without being real, where poor ghosts, breathing dreams like air, drifted fortuitously about . . . like that ashen, fantastic figure gliding toward him through the amorphous trees.
