Although science has long concluded that dreams are a kind of neurological behavior, in fact, for myself, dreams are like a supplement to a day and a second life. People say that what we think during the day, dream at night, and do during the day will often be dreamed again at night, without the constraints of reality, and this scene may be what we really hope. After Li Yu was captured by the Song Dynasty in the Southern Tang Dynasty, although he was not short of clothes and food, he was mentally tortured. Only in the dream can he relax himself, instead of forcing a smile, and there will be "I don't know who it is in the dream, greedy." Feelings.
If it is not enough, just add the following example.
Zhuangzi dreamed that he had become a butterfly. When he woke up, he wondered whether he had dreamed of a butterfly or whether the butterfly had dreamed of himself.
How much do you know in your dreams?
I don't know if I am a dream guest, but I am insatiable in one day.
Attachment has a dream
Golden Millet Dream―sheer daydream
I will know who dreams first all my life.
