An implied adjectival phrase

The protagonist, Philip, got the appointment as assistant house-physician at St. Luke's.
But he came to know he made pregnant his middle-aged friend's eldest daughter Sally.
Two days afterwards, during which he thought of several possible futures, he met Sally.

"Well, how have you been?" he said at last, with a little smile.
"Oh, it's all right. It was a false alarm."
"Was it?"
"Aren't you glad?"
An extraordinary sensation filled him. He had felt certain that Sally's suspicion was well-founded; it had never occurred to him for an instant that there was a possibility of error. All his plans were suddenly overthrown, and the existence, so elaborately pictured, was no more than a dream which would never be realised. He was free once more. Free! He need give up none of his projects, and life still was in his hands for him to do what he liked with. He felt no exhilaration, but only dismay. His heart sank. The future stretched out before him in desolate emptiness.
[Of Human Bondage by Somerset Maugham]
I'd like to know if "of his plans" is implied after "the existence."
Thank you in advance for your help.
