What dreams are accurate? A few days later, what I dreamed happened. No need to interpret dreams. Why is this?

Theoretically, there is no such dream, because dreams are dreams generated by the subconscious mind randomly choosing analogies or characters and organizing the plot in disorder according to the information you receive. If the dream that appears in this mode wants to be exactly the same as what you will encounter, the possibility is infinitely close to zero.

I suspect that you guessed it only after watching the American TV series Death Comes. Such a situation simply does not exist.

Once a mathematician (it seems) put forward a reasoning that if a monkey is tied to the piano and given infinite life, it will eventually play a classic Beethoven song, which is the inevitability of disorder in mathematics.

If you have an infinite life and can dream every day, you will eventually have a chance to predict what will happen in advance by dreaming. This is not making fun of you, but the probability in mathematics.

I hope my answer can meet your needs.
