创伤最隐秘的破坏，不是痛苦本身，而是悄悄拆散了那个连续的"自我感"。
"Trauma results in a fundamental reorganization of the way mind and brain manage perceptions. It changes not only how we think and what we think about, but also our very capacity to think."
书里有个扫描实验：让创伤幸存者回忆事发场景，结果大脑的自我感知区域（内侧前额叶，即"默认模式网络"的核心）出现异常——那里本该是感知"我是谁""我在哪"的地方，却陷入沉默。
"Many traumatized people find it impossible to be in the present; their hypervigilant systems are too focused on threat to allow them to simply 'be'."
康复的核心不是重新讲述故事，而是帮助神经系统慢慢相信：危险已经结束了，那个"我"可以回来了。
