Specifically, psychologists define self-talk as verbalized thoughts directed toward yourself or some facet of your life.
具体来说,心理学家将自言自语定义为针对自己或生活某个方面口头化思考。
So, going back to the sentence, we have " Silence" – that is, not making any sound or noise – " is only frightening" – is only scary – " to people who are compulsively verbalizing" – that is, who can't resist saying their thoughts out loud.
所以,回到这句话, 我有“沉默” ——也就是说,不发出任何声音或噪音——“只是可怕” ——只是可怕——“对那些迫性语言人” ——也就是说, 谁不能拒绝大声说出他想法。
