Use your logic to analyze the horror within it

1. Age
I got on an express train, probably around 10 minutes before midnight. At a midway station, a man also boarded the train. After the doors closed, he seemed to suddenly regain awareness and began looking around at the faces of the passengers.

"Forgive me for my ignorance, may I ask if you are 28 years old?" he asked me.

"Yes, but how did you know?" I asked in return, but he ignored me and continued talking to others.

"Are you 45 years old?"
"Yes, that's right."
"Are you 62 years old?"
"How did you know?"

He repeated this kind of dialogue with passengers who seemed unfamiliar to him. It seemed that this man had a special ability to know a person's age just by looking at their face. At this point, there were about 15 minutes until the next stop. The passengers, including myself, all cast curious glances at the man until he reached the last lady.

"Are you 50 years old?"
"Yes, but in five minutes I will be 51!" the lady replied with a smile.

Suddenly, the man's face turned ashen, as if he were shocked to the extreme.

Answer: The man's ability was not to see the age of others, but their lifespan. The lady would turn 51 in five minutes, and with 15 minutes until the next station, this meant that within the next 5 minutes, everyone on the train would die in a major train accident.

2. Photographing Notes in Africa
This happened when I was photographing landscapes in Africa. At the time, I used binoculars to see a large tree far away (not a baobab, just a normal tree). There were ten local people up there, looking downwards.

I followed their gaze down and saw a group of lions lounging calmly. Near them lay a hat on the ground.

I looked back at the people in the tree, and they were all wearing hats of the same style as the one on the ground.

"Haha, what unlucky folks, the hat just happens to fall near the lions. There's no way they can get it back now," I chuckled, turning my binoculars in another direction.

Answer: Since they were "all" wearing hats of the same style, it meant that no one's hats had fallen. In other words, the original owner of the hat that fell had already been eaten by the lions.3. Dreams I am a man who has comprehended the way of dreams, possessing the special ability to act completely freely and fulfill my wishes in my sleep. Therefore, my nightly dreams are a completely free paradise for me. The only downside is that I lose the sense of smell and taste in my five senses. For someone like me, jotting down the contents of my dreams that I haven't forgotten in my "dream notebook" has gradually become a routine thing every morning. Whenever I read, it always rekindles that immense joy. Whenever I talk to my brother sleeping beside me about my dreams and show him my dream notes, he always feels extremely envious. At such times, I always tell him: "That's because your cultivation isn't enough!" To quickly record the dream, tonight I kept my notebook and pen by the pillow without telling my brother and lay down under the covers. When I came to my senses, I realized I was on a battlefield, filled with the sound of gunfire and bullets scraping everywhere. "Heh, having a dream like this isn't bad. Let's go on a killing spree!" I picked up the guns scattered at my feet and started firing wildly at my target. But unexpectedly, it didn't feel very satisfying, so I focused and started thinking about the next dream. Watching my gun gradually transform from the inside out into a Japanese sword, it felt very skilled, and I immediately raised my blade to slash at the enemy in front of me. It felt amazing! I never expected that chopping people could be such a pleasurable thing. I swung passionately until I stabbed my enemy until it looked like a beehive. Watching him cry out in sorrow and fall to the ground, filled with intense blood, I still ignored it and kept stabbing. Soon, I finally felt fully satisfied. Alright, I could almost leave the dream and wake up. I had to quickly record this in my dream notes. Answer: From the start, it was said that in dreams there was no sense of smell or taste, so why could I feel the "intense bloodiness permeating the air"? The obvious cause was that the protagonist confused the dream and sleepwalking, and in a confused manner, assassinated the person sleeping beside him (his younger brother).
