Why Does BFDI Laugh Sound So Contagious?

For as long as I can remember, my family and I have been living in an underground basement that's completely shut off from the outside world. My parents have told me that the zombie apocalypse is terrorizing the outside world. The air is completely plagued with the zombie virus, and we'll die if we ever leave the basement. In order to save the supplies—which are already dwindling, to begin with—I've starved myself to the point I'm all skin and bones despite being only 18 years old. When I realize that there's only one last can of food left, I leave behind a suicide note. "Mom, Dad, now there's one less mouth to feed. You'll last a few more days." After that, I slit my wrist right away. Once I'm dead, my soul phases through the thick and heavy metal door. Bright sunlight illuminates the entire world. It's a beautiful, peaceful world filled with greenery. I can even hear birds chirping in the distance. Mom, Dad, and a bunch of people are throwing a barbecue party on the lawn. The mouth-watering smell of food being grilled permeates the air. So, it turns out that the zombie apocalypse is just a lie that's designated to trap me inside the fortress. I'm the only one who has died in this sunny, peaceful world.

Everyone in class can hear my thoughts, but there's a catch—the "thoughts" they hear have been deliberately altered. During the exam, while I swiftly fill out the answer sheet, the rest of the class stays put. They eagerly wait to hear the answers in my head. [The answer for this is C, of course. These questions are exactly the same as the ones Ms. Clarke revealed to me. I'm going to be the top student again without even breaking a sweat!] Everyone else immediately copy my answers. Ultimately, apart from me, they all end up failing the exam. During our swimming class, my leg cramps, and I start sinking underwater. I try to scream for help, but my classmates hear something entirely different in my head. [I'm going to act like I'm drowning and see who's the idiot who jumps in to save me. Hahaha!] In the end, they all watch indifferently as I drown. My eyes open again. I've gone back in time to the day of the exam. This time, I can also hear these "thoughts" of mine that have been altered.

My roommate sets me up. She deliberately forces me into a death-trap survival game. As I shut my eyes and wait for death to take me, I realize that the game's bosses can read my mind. "Look at the blood spurting from this baby doll's neck. It's like a fountain of pee." The baby doll is baffled. It's about to launch its ultimate move, but it falters. "Man, look at how this guy is still sweeping the streets when he's so old. Does he not have a pension?" The old man is about to swallow me whole, but he suddenly gets a heart attack. An ambulance takes him away. "Oh, so this is the amusement park's owner. Oh, dear god, he's handsome, albeit a little skinny. I can send him flying with a kick!" The handsome owner's expression darkens. He instantly takes off his shirt to reveal his washboard abs. "Do you still think I'm skinny?"

I had a perception disorder that messed with how I saw and felt stuff. So when I got dropped into a horror game, everyone else freaked out trying to survive— Me? I thought I was in a dating sim. I raised a young fae like she was my kid, fell for the vampire count, and treated the undead like my in-laws. The first time I saw the vampire—face torn up, soaked in blood—I straight-up blushed. "You're really handsome." He froze. Then, low and uncertain: "Am I... really handsome?"

In a music competition show, my rival unexpectedly played the melody I had in my mind before I could. Shocked, I confronted her, asking why she plagiarized me. However, she turned the accusation against me and said, "You said I stole your work, but do you have any proof?" However, I was unable to provide any concrete evidence. Thus, I was labeled as a bully and a plagiarist, ultimately meeting a tragic end. Even in my final moments, I couldn't figure out how she managed to steal something from my mind. When I opened my eyes again, I found myself back on that same stage. Seeing that my rival was about to play her part, I stopped her and said, "This time, it's my turn to go first."

My coworkers and I are forcibly dragged into a bizarre game with the initial title displayed as "War of the Plants". Everyone crowds around to choose camps or safe houses with abundant water resources. I am the only one who picks a plastic apartment in the desert with no water or electricity. My female supervisor mocks me in front of everyone, saying I must be out of my mind. No one is willing to team up with me, and they even bet I won't last three days. When choosing abilities, everyone rushes for practical powers like spatial storage or metal control. I, however, choose reverse photosynthesis that allows me to gain energy from air humidity. Everyone immediately mutes me in the game. Clearly, no one wants to hear my desperate cries for help later. But when the system revokes team permissions and administrator functions, everyone is stunned. The game's name is reset to "Magnet Apocalypse".
