When is the best time to dream?

Explain dreams from the current scientific point of view, that is, what you think or do during the day is deeply imprinted in your brain. Things like this will appear when you sleep at night. But science is still unconvincing about divination. What the ancient Duke Zhou said is also true, and it is a kind of summing-up experience left by the ancient people to future generations. The ancients observed astronomical phenomena, and linen fortune-telling was also very accurate. The ancients invented the yin-yang gossip, which was first used to predict what would happen next. The historical tragedy that shocked the world, the world's largest ship Titanic hit an iceberg on its maiden voyage. After scientific investigation, many people dreamed of the tragedy of ship sailing in their sleep the night before, so many people canceled their trips. The result is to verify the facts!
