What is the "inverted dream" that Buddhism often says?

First, I don't understand the impermanent truth, and I recognize the false as true;

Second, lust for worldly pleasures, not understanding that desire is the root of pain;

Third, I don't understand that everything in the world is illusory and impermanent, and there is no difference in essence, so there are many opposing delusions;

Fourth, I don't understand that "I" is also something that is aggregated by karma. Without self, it won't last long. In other words, the so-called "upside down dream" is to recognize falsehood and realize illusion.

Text introduction:

Dreams can be understood as "five elements are empty" (heart sutra), that is, the Diamond Sutra says, "Everything has its own way, like a dream, like dew, like electricity, so look at it this way."

Inversion means that the self does not correspond and violates the self.

Extended data

Source: Buddha said: The heart is free. There is no fear, because there are no obstacles. Stay away from upside-down dreams. After all, nirvana.

Interpretation: Hanging is a concern, and obstacles are obstacles. The obstacles in the world are worrying about career success, parents caring about their children, wives caring about their husbands and families, and so on. Because of obstacles, I am always afraid, because there is no power of Prajna wisdom. If you want to be clear-headed, you must learn Prajna. When you get to the other side, you must be clear-headed.

Stay away from upside-down dreams. After all, nirvana-right and wrong are indistinguishable, and the upper and lower are unclear, that is, putting the cart before the horse. After all, Nirvana refers to the highest and most complete immortal realm. Life is impermanent, and I don't know where I am. When I am chasing fame and fortune, I will be very happy if I get it temporarily, and I will be very painful if I lose it.

Therefore, the world is often in an upside-down dream. Dreaming at night is a dream, and waking up during the day is a dream. What real life thinks is true is actually a dream. So the Buddha said, "Life is like a dream". Only Buddha is a big dream. Although we are in a dream, it is valuable to do good in it. If you can practice the Prajna Paramita method, you can see that "the five aggregates are empty" and you can realize it in your dreams like a Buddha, thus proving nirvana.
