《红楼梦》第一回“作者自云”中谈到,用“梦”用“幻”等字,“是此书立意本旨”。从实际内容看,《红楼梦》不仅写了几十个梦,而且整部书写的就是一个大梦。脂砚斋说:“一部大书起是梦,宝玉情是梦,贾瑞淫又是梦,秦之家计长策又是梦,今作诗也是梦,一并风月鉴亦从梦中所有,故《红楼梦》也。” “A Dream of Red Mansions” for the first time, “from the cloud,” said, with “dream” with “magic” and other words, “is the purpose of this book conception.” From the actual content, “Dream of Red Mansions” not only wrote dozens of dreams, but the whole book is a big dream. Zhi Yan Zhai said: “A big book is a dream, a treasure is a dream, Jade prostitution is a dream, Qin family planning long-term strategy is a dream, this poem is also a dream, together with the moon also from the dream Therefore, ”Dream of Red Mansions" also.
