I don't know where the sourberville got his definition from, but i've never heard of that use of histrionics. Histrionic is actually an adjective not a noun, its used to describe actions that are intentionally dramatic, more specifically, actions dealing with acting or theather. "Histrionics repeats itself all over again" refers to the first line where the dramatic event of the boy crumbling is viewed for a number of times.
The lyrics depict an event in a theatrical manner, as if the narrator were watching a play of some event that heppened. This event could have been involving him, but the significance is that he constantly watches it over and over as if it was being acted out infront of him.
