Hu Xing knew that she had entered Xia Wenyuan's dream. It was Xia Wenyuan's consciousness body sitting on the shore fishing, and the reflection in the water, she couldn't tell whether it was the intruder or a normal shadow.

She knew she couldn't alarm him at this time. A dreamer, once disturbed by an external shock, his dream space will collapse like a building block accidentally knocked down by a child.

Hu Xing asked Aoki what to do next, but when she turned around, she realized that Aoki was not behind her at all.

This frightened Hu Xing, just like a child wandering around the street and suddenly finding that his parents were gone.

She tried to walk back the way she came, but she couldn't find the door that connected the two planes. At this time, he couldn't disturb Xia Wenyuan, and he had nowhere to go, and a feeling that was even more terrifying than not waking up in his own lucid dream struck.

She didn't dare to take one more step forward, which would disturb Xia Wenyuan. When she wanted to retreat, she found that there was no road behind her at all, no matter how she turned around, her vision was the same, the turquoise reservoir and Xia Wenyuan were always in front of her, and even if she walked backwards, the distance of her sight would not change.

Hu Xing stood here quietly like that, but she didn't know where she was standing, as if she was on the edge of Xia Wenyuan's dream.

I don't know how long it took, but a little dark shadow passed over the mountain in the distance. A bird flew quickly towards this direction, and when it flew to the surface of the lake, Hu Xing saw that it was a crow, not some water bird.

Hu Xing laughed as if she had seen a long-separated relative, and the crow with a broken mouth, a glutton, who often slaughtered her mercilessly by holding her handle, seemed so kind at the moment.

The crow flew close to the surface of the water, circled above Xia Wenyuan's head, and croaked a few times. The reflection in the water seemed to sense the danger and suddenly dived into the deep water. However, the water in the library was so clear that there was no room to hide. Hu Xing could clearly see Xia Wenyuan's shadow swimming along the pebbles at the bottom of the reservoir into the distance. But its feet were still in the same position where Xia Wenyuan was fishing, so the shadow under the water was stretched longer and longer.

The crow croaked, soared into the sky, then turned down, and a thump plunged into the water, following the shadow's head quickly. When viewed from the water, it looks like the reflection of a black plane gliding in the sky, and the elongated shadow happens to be the wake of the plane.

The shadow seemed to have no strength, and the longer it stretched, the farther away from Xia Wenyuan's consciousness body, the slower it swam. But the crow was not in a hurry to catch it, and followed it in no hurry. When he reached the opposite shore, the shadow propped up the reef with his hands on the shore of the lake, and his head peeked out of the water, as if gasping for air.

Only then did the crow croak, and then it pounced, grabbed the shadow by the shoulders with its claws, and flew up through the water, circling for a while, and then flying into the sky.

The crow flew higher and higher until a small black dot remained. The shadow was stretched longer and longer like a black lasagna, and as the height increased, the shadow became lighter and lighter, from a black shadow to a mist, like the smoke of a farmhouse. Eventually, it was blown away by the wind like green smoke and disappeared into the world in front of Hu Xing's eyes along with the crow.

"It's finally been wiped out!" Hu Xing muttered to herself, like she had just finished watching a thrilling movie, still stupidly waiting for easter eggs.

"Not yet, it's with your grandfather's consciousness, and I haven't found a way to completely destroy it without harming your grandfather." Aoki suddenly appeared in front of it.

"You're finally here." Hu Xing let out a sigh, "I thought you left me here, and I couldn't go out until my grandfather's dream collapsed!" ”

Aoki smiled: "You're still too nervous, if you can find the way you came, you can find the way back." ”

"Am I going to feel my own brain waves?" Hu Xing asked.

"From a scientific point of view, it's incomplete to say that brain waves are just a better way to understand." I don't know when, Professor Mei suddenly appeared. He looks a little strange, exactly like Albert Einstein. This is probably his subconscious impression or ideal of himself.

"It's a good dream, it's the first time I've been in someone else's dream." Mei Yiqiu looked around, and then said to Hu Xing, "You are already very good, you can find the passage to another dream by yourself, but I can only let Aoki bring it in." ”

Aoki said, "The professor's deep self-hypnosis is not something that ordinary people can do, but they take a different route. In terms of mental strength alone, you are already very strong, much more powerful than some people who have studied for a long time and still can't touch the door. ”

Hu Xing said: "How can I compare with the professor!" But the professor is so powerful, why don't he learn lucid dreaming and dreaming? ”

Mei Yiqiu shook her head and said: "I don't want to waste time dreaming, I learned self-hypnosis to improve the depth of thinking, and I can more calmly cope with the difficulties of not resting for days and nights in the laboratory." However, today's experience has helped me to better understand human consciousness. ”

"Professor, you just said that brain waves are inaccurate, so what exactly? How do I find my way back? Hu Xing asked.

Mei Yiqiu said: "When people are dreaming, the subconscious construction of the dream space is to retrieve a large number of brain memories, at this time the various memory areas of the cerebral cortex are very active, and the brain waves are also very active. But I guess brain waves are just signals, they don't form a channel that you can walk through. This passage is supposed to be the result of the unstable fluctuations of the space when constructing the dream. ”

"The space in the dream is more like carving out a temporary space in our three-dimensional world. It is supposed to be transformed at the singularity, like a miniature Big Bang. It's just that the level is too small for us to perceive. The energy fluctuations caused by the explosion will form many small wormholes. This kind of wormhole is too small to have no effect on the real material world, but it can allow consciousness to pass through, and the energy required for consciousness to pass through comes from the spiritual power of the human body, or consciousness energy. ”

"Somebody, consciously, if anyone can stabilize their dreams, it's an ever-expanding universe, and his own subconscious mind is the master of this universe." Mei Yiqiu thought for a while and said, "I think that in different dimensions, there must be the birth and annihilation of space all the time, in fact, it is the birth and annihilation of each universe. The universe in which we live is one of them. ”

Hu Xing had just read a few books on the universe, the theory of relativity, and quantum mechanics, and when she didn't seem to understand it, she asked, "Professor, are you saying that this world is actually someone's dream?" ”

"It can be understood that way." "If God exists, aren't we in the dream he created?" ”
