For example, we are shopping with friends in the street, and suddenly you have a flash of light and the scene in front of us is very familiar. You even know that it will rain in the sunny sky next second, and neither you nor your friends have an umbrella. You fled to a shopping mall in a panic and happened to meet your ex-boyfriend and his girlfriend shopping. You're thinking, it's clear and cloudy in Wan Li. The next second, it's raining, and you hide in the nearest shopping mall. I looked up and really saw my ex-boyfriend.
Scientists believe that human beings dream because our consciousness is stimulated by some memories when we sleep, or when we delete some memories, we present them to you in another way. However, these are just scientists' guesses. Although human beings are now very advanced in science and technology, we still know very little about the human brain. Therefore, there is no way to make a very reasonable explanation for why we dream realistically.
As early as more than half a century ago, some scientists said that space is multidimensional, and human beings are in three-dimensional space, with at least 7-8 dimensions above us. Theoretically, high-dimensional space can control low-dimensional space downward, but low-dimensional space cannot communicate with high-dimensional space. However, human dreams may be the only channel to communicate with high-dimensional space. In science, this dream is also called by scientists? Weidong? .
When we fall into a deep sleep, our consciousness will enter a high-dimensional space, so we experienced some strange things there. At the same time, because the low-dimensional space is created by the high-dimensional space, we will also know something about the future.
There is a science fiction film called Interstellar. In the film, the protagonist enters the five-dimensional space and finds that everything that happens on the earth can be consulted at will, whether it is the past or the future. So he went back to the past and talked to his daughter, hoping that she could leave her who didn't take part in the interstellar mission, so everything would change.
The reason why we feel that dreams are real, perhaps because we will have some overlapping scenes when we are in contact with high-dimensional space, but in reality, because we accidentally touch a fragment of the future in high-dimensional space, we will feel deja vu.
Of course, although this statement is a speculation, it is not completely without scientific basis. Through the study of quantum physics, scientists have found that quantum can also explain human consciousness well. For example, human consciousness may successfully enter high-dimensional space through quantum entanglement. There are still many unknown mysteries in the vastness of the universe. Maybe one day, we will really uncover the truth of dreams.
