Chapter 13 Section 12

I suddenly opened my eyes, this is the living room, Matsuura is right in front of me, Tendo and Kaori looked over from the sofa in front, showing full of interest. "--I am asleep?" While asking, I subconsciously covered my mouth.It's okay, no saliva came out. Kaori said with a creaking smile, "Oh, I slept soundly." Hearing what she said, I watched the situation at the drinking table, and it seemed to be similar to what I remembered.The discussion at Oiso's table was just as loud as before, and I could hear it clearly here, and it was the same as before I was caught by the Sandman.

"I was just dreaming, Tatsumi." Tiantong said.With such a reminder from him, it seemed that he had really dreamed of something. "What's wrong?" "All of your states exhibit the hallmarks of REM sleep." I was shocked by what he said.I have seen on TV that the so-called rapid eye movement sleep can be observed through the eyelids of a person in a sleeping state as the cornea bulges and twitches left and right.There was a sudden rush of shame at the thought that I had been in that state and had been seen by others. "But I only slept for a while."

I forcefully defended myself, and Kaori took up the topic. "Ah, but Tatsumi-sensei, isn't there a saying that says, no matter how long the dream feels, it's actually just a moment." "You mean a dream in Handan, right?" Matsuura just seized the opportunity to show off his knowledge, but Tendo refuted his claims. "It's true that you hear it a lot, but it's wrong." "Ah, is that so?" Kaori blinked.Tendo leaned out. "Human sleep can be divided into two types: rapid eye movement sleep and non-rapid eye movement sleep. Dreaming will only be during rapid eye movement sleep, and it will last for about fifteen to thirty minutes. Dreaming is generally only like this For a long time, at least not for a moment.

"Think about it, why do people dream? Ultimately it's just the person's brain playing out these scenes. So even when talking in a dream, the parts of that person's brain that process language are active. There is not much difference between waking and sleeping states. If you speak ten seconds in your dream, it will take ten seconds for your brain to process the language. "So, at least in terms of processing speech, the sensed time in the dream is the same as the time in the real world. The same is true for other things. And it is completely impossible to process everything in the dream in an instant, considering the size of the brain. .”

Kaori's expression was still somewhat dissatisfied. "But Tendo, isn't it often said that humans only use three or a few percent of their brain capacity. So, the human brain can actually process a lot of things fairly quickly, but it can't do that during waking hours. This kind of ability-that, so, to borrow the example just said, the language processing should have been carried out at a faster speed, but the speed of the mouth, ears and other external organs can not keep up, so it can only maintain this speed when a person is awake .But in a dream, you won’t be restricted by these external organs, so you can play at a speed that is completely incomparable when you are awake—can you say that?”

"daydream?" Kaori was convinced by Tendo's words, but she immediately showed an expression of refusal to admit defeat. "However, isn't there a saying that short-distance... such as a 100-meter race, the surroundings seem to be in slow motion when they are running? This is also the case where the brain is running faster than usual , the surrounding movement seems to be relatively slow—is this inference unreasonable?" "Ah, yes, yes." Tendo nodded triumphantly. "But that's just a kind of pleasure for runners, that is, brain tranquilizers. I heard that sprinters have to hold their breath before running. In order to maximize physical capabilities, the brain must first be deprived of oxygen, so that the brain The activity of the brain will temporarily decrease, and in order to compensate, it will secrete a brain tranquilizer to numb the perception. On the other hand, it is the cerebellum that controls the movement at this time—"

Kaori shook her head. "That's not the case. Well...an example, in a traffic accident, the outside world seems to be in slow motion at the moment of the accident." "It's the same in this case. In an emergency, in order to alleviate the expected pain in the near future, people secrete brain tranquilizers in advance—" "No, although there is such a possibility, but the more important thing is that the brain is running faster than usual at this time, and I want to move the body faster, but the body can't handle it, so I feel sluggish—isn't it? "

At this point, Matsuura, who had been looking for an opportunity to insert just now, spoke. "Ah, as expected of Kaori. I also agree with what you just said. It's exactly what you said." I was suddenly a little disappointed, thinking about why the atmosphere had become like this, when Oiso's roar came at the right time. "Hey, let's go to the tower to see. Kaori and teacher, let's go together." "Ugh?" Kaori looked up at the ceiling with an unhappy expression. "Ah, that's right. I made an appointment with the teacher during the day to go up and have a look together."

"Ok." I answered.Seeing the tower from the outside, knowing that you can go up to the top floor by going up the stairs, it is human nature to want to go up to see what's going on.To Kaori, that tower is what the Tokyo Tower is to the citizens of Tokyo. "Then I will take my leave first." Tendo narrowed his eyes and softly resigned. "I didn't say I was going, and I'm tired today. Sorry." "See you tomorrow." He took the cigarette and lighter from the table and walked quickly to the stairs.Kaori watched him go with her mouth open, regained her spirits, and grabbed my arm.

"It's okay. Teacher, let's go." "I also need to go." Matsuura stood up holding the wine glass. "Are you alright?" I was asking, of course, about the burn on his left hand.Although it's too late, can he drink like this? "Alcohol can act as an anesthetic. Anyway, lying on the bed now, the pain will be so painful that I can't sleep." Matsuura asserted that there was a kind of embarrassing frankness in his words. Daiso and Xiuyi appeared from the kitchen carrying buckets, and there was a clanging sound.I was wondering what the sound was when Kaori explained it to me.

"It's ice water because there's no refrigerator on it." I see.Occasionally, the shaking bucket made a sound and splash.I glanced inside as I walked past the two of them, and there were several cans of beer in cold cans in each bucket. "Do you want to drink?" I asked Kaori in surprise. "It's just nighttime for that group of people." Yeah, I've put the whole thing behind me. Although I am about to climb to the top of the tower I am looking forward to, I am not happy.After all, I have been drinking endlessly since the evening. I didn't intend to get drunk, but when I walked up the stairs, I fell into a leg.Looking up, the stairs stretched straight up, and the outside of the handrails went straight to the ground, and it was dark under the feet, and there were water shaking from Xiuyi and his buckets everywhere. "ome." Daiso's voice came from above the stairs. He probably didn't mean 'you', but 'heavy'.Indeed, actually carrying that kind of thing upstairs. When I got to the second floor, I suddenly felt very tired.So I walked through the arch in front of the corridor and staggered into the sun room.The lighting here is only a small yellow light bulb, which is in stark contrast to the dazzling light of the day, and it is already dim.I sat on the sofa to rest for a while, and Kaori and Matsuura also accompanied me. "Are you all right, teacher." "I'm a little drunk today." After answering, I let out a sharp breath.As long as you stay still like this, it doesn't seem to be that painful. "That's right, it's a bit difficult to climb the stairs when you're drunk." Kaori looked at me, her eyes seemed to be asking me what to do.I waited for my breathing to calm down, and pulled myself together again. "Let's go."
