You could say Trump is facing reality (the way ordinary people live) for the first time in his life. Makes all the sense in the world. Trump is surely a master of projection we've seen, also his supporters seem to take on the trait muchly too.
"As a president and postpresident, however, Trump has rarely had to face criticism in person. He carefully curates his public events so as to almost never encounter critics of any stripe. His life is spent at a private club or on a golf course. He skipped every White House Correspondents Dinner as president. His rallies are filled with gushing supporters. He lives in a fantasy world in which Hollywood, the media, and political elites despise him—but the people love him.
Being in a criminal trial has forced Trump to leave that fantasy world. A man who has a desperate need to see himself as a domineering winner is forced to live in brutal reality where he is in the precarious position of being a potential felon.

Trump’s foes have every reason to relish the current moment. Both the outcome of the court case and the election are up in the air. It is entirely possible that he could win court cases even where his guilt is manifest (the example of O.J. Simpson, recently dead, should remind us of that). Trump could also win the presidency again, which would render almost all the court cases moot. (Even the ones that are in state courts—such as current Manhattan trial or the Georgia case involving Trump’s efforts to overturn the election—would fall into political difficulty, since it’s almost inconceivable that a Republican Supreme Court would allow a duly elected Republican president to be jailed in office.) So Trump’s current misery should be mined for every ounce of schadenfreude it currently provides.
However, the pathos of the scene before us shouldn’t escape notice. Because Trump’s true addiction is to his self-regard—and because his ego is a black hole that devours everything around him—there is no reason to hope for improvement. You can always kick a drug addiction. But there is no 12-step program that will cure the true sickness that ails Trump’s soul."
