Another example is Chekhov's Fanka, which tells that nine-year-old Fanka was sent to the shoemaker Ariadne's home as an apprentice three months ago and suffered a lot. Write to grandpa in the country before Christmas, begging him to have mercy and take him home. But there is no specific address on the envelope, only the words "country grandfather". When Fanka put this letter with no address into the mailbox, the author not only did not regret it, but added a sentence: Fanka fell asleep beautifully and had a beautiful dream that the letter was safely delivered to his grandfather who was reading aloud. On the one hand, the letter was thrown into an empty place, on the other hand, it was the sender's dream. This strong and sharp contrast makes people suddenly fall into a kind of heart-wrenching pity, just like a falling mountain and an empty valley ringing, which is unforgettable. In addition, according to statistics, the book A Dream of Red Mansions alone has written 32 dreams, big and small. Describing the illusion of a character can also reveal the inner activities and spiritual world of the character. For example, Andersen's Little Match Girl describes a lot of hallucinations. Warm iron stove, delicious roast goose, beautiful Christmas tree, kind grandmother ... what a hungry little girl can't get in this world can only be obtained from illusion. With a kind and beautiful heart and no longer extravagant hopes, she left this world without light, warmth and her place. Another example is the movie The Sparkling Red Star, in which Dongzi misses his father and yearns for a better life. The picture shows the illusion that Yingshanhong is in full bloom all over the mountains, and my father leads a team back. Now many students like to write dreams, and there are indeed many excellent works written well. However, it must be pointed out that many students did not grasp the true meaning of dreams in their compositions, but only wrote dreams in pursuit of novelty and in order to write dreams. For example, an exercise about setting off firecrackers on the Lantern Festival actually said that I dreamed that I "turned into a string of red firecrackers and set them off in the street". It doesn't mean anything, but it doesn't make sense, because in any case, people can't turn into firecrackers. Because dreams and hallucinations are closely related to the characters' inner activities, they are the characters' understanding of life and experience in the subconscious psychological state, and also a kind of "refraction reflection" of the characters' thoughts, feelings, moral qualities, wishes and concerns. Therefore, when describing dreams and hallucinations, we should closely follow the situation and psychology of the characters, do not deliberately pursue strangeness, and avoid serious disconnection from the description of real life, so as not to lead to mysticism.
