"Alright, now let's talk about that symbol of yours."

Professor Mei Yiqiu finally got to the point.

He picked up a pen and drew a regular triangle on paper: "This triangle represents the space we are in. Then he drew an upside-down triangle on it, with the vertices of the two triangles meeting, "This triangle represents another space." Now, the two spaces are connected, but they are not connected. Moreover, there is only one point at the junction of the spaces. ”

"Do you know the meaning of 'dots' in mathematics and physics?" The professor asked himself, "In geometry, 'points' cannot be defined. Trying to define a point will lead to the abyss of repetitive definition and inverse logical definition. But spatially, we can think of a point as a 0-dimensional object. ”

"0 dimension, that is, there is no dimension, not even the lowest dimension. Remember, the singularity of the universe is not a point in the mathematical sense, the singularity is arbitrary dimensional, it is not 0-dimensional. "Matter and energy exist universally in all dimensions of the universe, but not in dimension 0. If two triangles are connected not by a point, but by an edge, we cannot be sure how they interact with each other, because we cannot be sure whether the two triangles represent a plane or a three-dimensional, but we can be sure that there must be a wide exchange of matter and energy between them. But now, the two triangles are connected by only one 'point', which is a dimensionless space that cannot pass through any matter. ”

"It seems that the two triangles will not have any connection, so what is the point of connecting them together?"

At the critical moment, Mei Yiqiu made the old mistake of selling Guanzi again.

Aoki reluctantly picked up a meaningless sentence: "It's always meaningful to be connected!" ”

"yes, of course it makes sense." The professor was probably glad that someone was listening carefully to his theory, "because if they were separated, they would become two isolated universes, and it would really be meaningless." They are connected by only one 'point', and although no matter can pass through, they are still one and belong to the same universe. As long as they are in the same universe, there is no two spaces that do not affect each other. ”

"And how do they affect me?" Mei Ziqing was not criticized by the professor for interjecting before, but she also became bold at this time.

The professor said: "As a living being, you should not forget that there is such a thing as 'consciousness' in our universe, which is similar to what metaphysicians call the soul. Consciousness has no mass and is independent of matter. We have it, but we don't know how it works. Only this kind of thing without mass can pass through the point of 0 dimensions and reach another space. ”

"Oh, I see." Mei Ziqing cherished the opportunity to speak like a student, "You just mentioned dreaming, which means that people's dreams are also another real space, and there is a connected 'point' between it and our real space, and only our consciousness can go to the dream through this point without dimension. So, when we dream, it's not actually illusory, but our consciousness has traveled to another dimension? ”

"Well, that's what you can understand." "But dreams are illusory to us, because our consciousness doesn't completely leave our bodies and go somewhere else, and if we do, we won't wake up." Just like the quantum superposition, when we dream, consciousness should exist in two spaces at the same time. ”

"Of course, some people may be exceptional." The professor winked mysteriously at Aoki.

Mei Ziqing obviously didn't understand this passage very well, but the professor seemed unwilling to go any further, but picked up the pen and added a vertical line through the vertices to the two triangles.

If you think of this symbol as an hourglass, this line undoubtedly represents the passage of time. But the so-called passage is only relative to a single space, if you look at two spaces as a whole, you will find that time does not increase or decrease in total. ”

As he spoke, he picked up the hourglass on the table, put it in his hand, turned it upside down, and poured it back again. The sand in the hourglass flows from one end to the other, and from that end back to this end, but no matter what, they are just that, and they never change.

"You're saying that time in dreams and reality are interchangeable?"

"It's not just about time, it's about space and everything. Just like this hourglass, the sand in it represents the time that is possessed in this space, and also represents all the material that fills it. When time passes to the end, there is not a grain of sand left, and unless the hourglass is turned upside down, the space loses its meaning. ”

"Just as each of us is going to die at some point, death means that 'my' time has come to an end. In the eyes of others, the world still exists, but for the dead, the world has no meaning, and the space collapses. ”

"But consciousness has entered another space that has been 'filled', and only by turning the hourglass upside down can it start again?" Mei Ziqing thought it was amazing, "That's why those pharaohs in Egypt thought of building two identical pyramids and waiting for some mysterious force to turn the 'hourglass' upside down?" ”

"This is just a corollary of the mirror pyramid and this symbol, and it can be regarded as a hypothesis. Perhaps the priests of ancient Egypt had some kind of way of controlling dreams, and they got a revelation from it to build something like a pyramid. The professor replied, "When I come back from Copenhagen, I may have more useful information and evidence." ”

"So, this symbol was handed down by the priests of ancient Egypt?" Aoki asked.

"It's hard to tell when the symbol originated." "We can only judge the symbolism of this symbol: space, time, and our consciousness," the professor said. If we don't include the legendary worlds such as the Netherworld and Heaven, the only independent space that human beings know to reach can reach is the dream realm except for the reality we are in. ”

"So, it must have something to do with dreams?"

"At least it has something to do with the imagery of dreams."

"Is there anything specific, like something related to an organization or religion?" Aoki knew that the professor was very knowledgeable, so he thought about it, and said something specific, "Have you ever heard of an alliance related to dreaming and awakening, and it seems that there is also a profession to become a dream mentor?" ”

The professor shook his head and said, "I haven't seen this mark before, and I haven't heard of this alliance as you speak. But what you say reminds me of something. ”

The professor took several puffs of cigarette and adjusted his thoughts.

In fact, the concept of the collective unconscious was proposed long before Jung, and if we go back even further, the Chinese and European witches have long been able to skillfully use the collective consciousness for mind control. In ancient legends, people were bewitched by the night ghost, and after falling asleep, everyone had the same dream, and the dream continued, after which it was impossible to distinguish which was reality and which was a dream. ”

In order to prevent this from happening, some wise men have come forward to teach people how to discern the difference between reality and dreams, and they and their followers call themselves awake people. Their mission is to protect humanity from being led into the same dream. It is said that they do not need to know each other, they only meet in dreams, teach disciples and fulfill their mission. ”

Mei Yiqiu's large pipe was still burning, and the smoke from his mouth had filled the room.

Aoki seemed to see a new world in the gray mist. There is a zero-dimensional connection point between this world and him, and he only needs his consciousness to pass through it to see everything there.
