Is space-time continuous?

Everyone dreams, but almost everyone has many unsolved mysteries about dreams, such as why do people dream when they are asleep? Why do dreams often look strange? The scene in the dream is so clear and lifelike, did I do it in another time and space? Maybe everyone who wakes up from sleep will have such a question.

Many things about dreams and dreams are really puzzling! Even experts in brain science and mental science can't say they know everything. Is a person's dream what is happening in another space? It is estimated that everyone has had such an idea, and Bian Xiao sometimes wakes up from sleep and has such an idea. Because things in dreams usually make people feel very real, reasonable, story-telling and close to life, but we also know that it didn't happen or can't happen in reality. For example, if you like someone, you can't be with him for one reason or another in reality, but you can be happy with her in your dreams. When you wake up, you can't help but feel how wonderful it is to live in a dream, whether it is yourself and her in another space, and whether it is in that world. All this makes people have to daydream.

So is this really the case? Although the hypothesis of parallel universe and multiple spacetimes is also reasonable, some people believe in the world of reincarnation, and believe that everyone will have a different life in different spacetimes, but at present, at least in science, there is not enough theoretical, observational and experimental evidence to prove the existence of parallel universe and multiple spacetimes and the sixth reincarnation, and it is even more impossible to prove that there will be another you and me in other spacetimes, so the idea that a dream is something you do in another space can only be thought about, and nothing can prove that it is true and accurate.

To solve the mystery of dreams, we must rely on science. According to the current research on brain, neuroscience and psychological spirit, dreams belong to the spontaneous scene simulation of the real world by the brain, which is very random. Dreams will not be interpreted completely according to reality, but will only be linked to reality without constraints. So many things in the dream are unimaginable, such as people in the dream can fly, go to places they have never been, meet people they have never seen, and do something. In short, most of the scenes in the dream are imaginary and often divorced from the real reality.

The reason why dreams are like this is related to the solemn memory of people in the brain. When a person's mori memento mori appears in disorder in his sleep, the scene in the dream will also become disordered and inaccurate. However, dreams are also varied, which are related to people's psychology, people's concerns and things they do during the day. So people often say, think during the day and dream at night. Furthermore, dreams often reflect people's subconscious more than reality. Freud studied dreams with modern psychology. In his book The Interpretation of Dreams, he said that many dreams are also the manifestations of people's subconscious, such as sexual dreams in adolescence. Although adolescent children are ashamed to talk about sex, their physiological rhythm has already begun, and they are psychologically budding, so they will have some sexual dreams that make them shy!

Take Jia Baoyu in A Dream of Red Mansions as an example. Jia Baoyu dreamed of having sex with Qin Keqing. He should not have such an idea at ordinary times, but his subconscious sexual consciousness is already stirring! Sexy and full of mature feminine charm, Qin Keqing can arouse his sexual subconscious most, so he fell asleep after visiting Qin Keqing and had such a dream. Although this is the plot in the novel, it is very realistic.
