独影境

大脑在没有外界真实传感器输入时，自己跑代码渲染出来的“脑内微电影”。比如你坐在沙发上发呆，脑海里突然回放出昨天吵架的场景，或者幻想自己中了大奖。这是一种完全脱离当下物理现实的纯自我幻觉（Pure Hallucination）。

When the brain operates without genuine external sensory input, it executes internal code to render a "micro-film" within the mind. Consider sitting on the sofa in a daze, only to suddenly replay yesterday’s argument or fantasize about winning the lottery. This is a pure hallucination—a self-generated illusion entirely detached from the immediate physical reality.
