Trying to touch what was no longer tangible, struggling unhappily, undespairingly, toward that lost voice across the room.
Daisy’s “lost voice” across the room is the same exact idea as the green light across the bay. This confirms once again that Gatsby views the green light at the end of the dock as a symbol for Daisy.
The language Fitzgerald uses to describe Gatsby’s attempts to contact Daisy is similar to the how he describes reaching out for the green light at the end of the novel.
“the dead dream fought on as the afternoon slipped away, trying to touch what was no longer tangible” vs. “his dream must have seemed so close that he could hardly fail to grasp it”
The similar description of Daisy and the green light hammers home the point that the two mean the same thing to Gatsby; they represent his American Dream.
