What is detailed interpretation of this passage from The Great Gatsby ? (I need help with explaining "frightening leaves" "grotesque rose" "sunlight" "grass" " a new world""poor ghosts", why wilson is "ashen figure"?)

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

Explanation:

The paragraph given in question statement is from Chapter Eight. Starting from the line given, Nick has told himself that he couldn’t sleep because he is strangled "between grotesque reality and savage frightening dreams." Nick told that just as rose has an image of its beauty, so is Daisy “grotesque” in the same way. Gatsby has invested her with beauty which is the center of his dream.

Gatsby has lived "too long with a single dream"; without this dream, his life has become bizarre. In this new world, a world without his dream, Gatsby noticed a rose is just a rose and a green light is not more than a green light. So now Gatsby has been forced to grow up and the world seems im-material to him
