A frightening first episode

Following an evacuation during a sudden flood, Tobias, 45, developed intense fear, disorganised speech, and a shifting set of beliefs over two days — first that rescue workers were impostors, then that the flood was staged to trap him specifically. Four days after onset, his family reports the beliefs and mood have already started to settle, though he remains bewildered. He has never had anything like this before, and no substance use or medical illness is identified.
