With the theme of human brain activity, the plot of the story is very complicated, and the writing is more than half longer than other stories. In this revision, I found that there is no room for large-scale deletions, but only piecemeal deletions. The absence of sentences makes the text more concise and the development of the story more neat. After re-reading the whole story, I sighed: people are really stupid, they are creatures with very low intelligence, and it is difficult to judge even such a simple thing as reality or fantasy. As an advanced creature, your mind is really quite pitiful.

Perhaps, true or false, is not so important.Many troubles in life arise precisely to clarify truth and illusion. Who knows?Just as the story wants to show—the human brain is too easily disturbed by external signals!
