9:52 AM: Inside a certain school's classroom, the teacher was lecturing about statistics and probability.

"Excuse me, ma'am," I raised my hand.

"Yes?" The teacher inquired.

"May I go to the bathroom?" I asked politely.

"Sure, you may," she replied, then resumed teaching.

Leaving the classroom, I thought, "What a nice day," as I admired the blue sky and its beautiful clouds. "Descending to the first floor is such a hassle; why are we on the fourth floor anyway?"

I peered down, clutching the wall tightly. "So high," I murmured.

Here's the edited version with improved grammar and flow:

"Huh?" I gasped. Why am I falling down?

...

"Hey! Someone fell from the building!"

I struggled to open my eyes and saw the clear sky. "How beautiful," I murmured.

Then I questioned, "Why am I on the ground?"

...

Slowly, I raised my hand. Looking at my hand, covered in blood.

"Ah... I'm losing a lot of blood."

...

"Mr. Siah! Mr. Siah!" The teacher shouted, bringing me back to my senses. "Mr. Siah, is something wrong?" he asked.

I glanced at my surroundings; all my classmates were looking at me. "Umm... Can I go to the bathroom, ma'am?" I said.

…

Walking down the hallway, I muttered to myself, "What the hell was that? I'm certain I died back then. What the hell is going on!?"

I glanced at the wall, gripping it tightly. "I know... this is the place," I said, then turned around to find my best friend behind me.

"Dammit! I made sure I hid myself!" he exclaimed.

"What... are you doing?" I asked, feeling hesitant.

"I was supposed to knock you off," he said sarcastically.

"I see."

"What's wrong? Are you okay?" he asked, sounding worried.

"Yeah, don't worry," I reassured him with a smile, and we proceeded to the bathroom.

As we walked back to the building, I suddenly said, "Hey, can you go first? I forgot something behind."

"Oh, I can wait for you," he offered.

"No, no, don't worry about it," I insisted.

"Okay..." he said, then walked away.

Here's the revised version with improved grammar and flow:

Returning to the spot where I had fallen, I stood there, gazing up at the sky. "Hah... am I going crazy?"

"Why aren't you in your classroom?" a teacher asked, the same voice I had heard when I fell.

"Umm... Ma'am, it's a strange question, but have you perhaps seen someone fall from here?" I inquired.

"Fall? That would be tragic! Why would someone fall from here?" she responded.

"Oh, yeah, sorry about that, Ma'am. I'll be going then," I said, excusing myself.

Heading to the stairs, I reached the second floor when I heard a distant scream. Out of curiosity, I peeked to see students running—thirty of them. "What the hell, are they playing during class hours? They're insane!"

"They sure run fast, though," I couldn't help but admire, but then one of the students running approached the building. I stared at him.

"Hey! Don't run in the school grounds!" the teacher I had spoken to earlier shouted. The running student ignored her and headed straight for her.

"Why are you still running? Do you want me to report you to the principal? Hey... stop, stop!" the teacher panicked as the student didn't halt and jumped at her.

She screamed, "WHAT ARE YOU DOING!? Help! Someone help me!"

"Shit! Shit! Shit! What the heck is wrong with that student? Is he on drugs?" I exclaimed as I rushed downstairs. "Hey! Stop!" I shouted as I approached them, but then the student suddenly bit the teacher in her neck.

The scene you've described is intense and filled with suspense. Here's an edited version to enhance the narrative flow and readability:

---

"AUGGHGGHHH!!!!!" The teacher's scream pierced the air with pain and agony, drawing the attention of other students towards the commotion.

As the horrifying scene unfolded before me, adrenaline surged through my veins. Without hesitation, I lunged forward, attempting to pry the student away from the teacher.

"What the heck are you doing, man!" I exclaimed as I grabbed his shoulders from behind, trying to pull him away. His grip on the teacher was strong, barely budging despite my efforts.

He went for another bite, prompting me to shout in frustration and deliver a punch to his head. But he persisted, so I resorted to strangling him. However, he managed to bite my arm. "Aughh!!! You Motherfcker!!" I yelled in pain as I finally managed to push him away from the teacher.

Gasping for breath, I stared at him, my entire body trembling with fear. "What the hell are you doing?!" I shouted, but he merely tilted his head left and right.

"Shit!" I exclaimed as he charged at me again. I punched his face, but it had no effect as he pushed me down and aggressively bit my neck.

"AAUGGGHHHH!! WHAT THE HECK ARE YOU DOING?! STOP! STOP! STOP IT!!!!" I screamed, attempting to push him away, but he clung on fiercely.

He devoured my flesh relentlessly, teachers nearby rushing in to help, but it was futile. They too fell victim to his bites.

In the midst of the chaos, I struggled to stand, my entire body wracked with pain and terror. "Help… me… please," the teacher pleaded weakly before passing out.

I glanced at her, feeling a wave of pity, even as I held my bleeding neck. "I need to get to the infirmary," I muttered, slowly attempting to make my way there. "What the heck is going on? Is the world... ending?" I questioned aloud, just before the teacher who had helped me earlier shoved me from behind and began tearing into me, devouring me alive.

In the wild mess, the teacher who had helped me before turned into my enemy, attacking me and hurting me badly. Everything seemed to spin in a scary way. Pain shot through me as I tried to fight back against the strong attack.

I yelled out in pain, trying hard to push the teacher away, but they kept attacking me. Blood was all around me, and I kept calling for help. The sounds of my body being hurt and bones breaking filled the air, along with the angry sounds of the teacher.

My eyes started to go dark, and I felt weaker and weaker. I wondered what had caused all this horror. Was this the end of everything?

As I started to lose consciousness, I tried to hold on to any clear thoughts, trying to understand what was happening. But it was all fading away, taken over by the endless hunger and violence of the zombies.

With the last bit of energy I had, I whispered, "Someone... anyone... please help..." But my words were lost in the chaos, drowned out by the disaster of the zombie outbreak that had taken over.

I gasped for air, the remnants of terror still clinging to my senses as I found myself back inside the classroom. "What... what the hell is going on!?" I screamed in panic, my heart racing uncontrollably.

"Hey, are you okay?" My best friend hurried over, concern etched on his face.

"Mr. Siah, don't scream in my classroom! Do you want me to call your parents to the guidance office!?" the teacher thundered in anger, her voice jolting me further into a state of distress.

"No! Don't come near me! You don't understand! The... the world is ending! Zombies! Yes, those zombies are here!" I shouted, my words tumbling out in a frantic rush.

My best friend's reaction was swift. He landed a punch on my face, snapping me out of my panicked state momentarily. "Get a grip, man!" he shouted as he grabbed my collar, then gently held the back of my head and my cheeks, forcing me to look at him. "Look at me, okay... breathe, calm down."

"You don't understand! I saw it with my own eyes! That student suddenly ate the teacher alive! I was also eaten alive!" I cried out, the memory of the horrifying ordeal still fresh in my mind.

My best friend's grip tightened, his eyes searching mine for any semblance of stability. "Listen, Siah," he said firmly, his voice a steady anchor amidst the chaos in my mind. "You're here, in the classroom. Take deep breaths. We'll figure this out together, okay?"

I struggled to calm my racing thoughts, the images of blood and terror still vivid in my mind. Slowly, with my friend's reassurance, I began to regain a semblance of composure, though the fear and disbelief lingered like a dark cloud over my sanity.

With my best friend's grounding presence and his calming words, I gradually managed to rein in my frantic emotions. The surreal experience of being back in the classroom, juxtaposed with the vivid memories of the zombie outbreak, left me in a state of disorientation.

I took deep breaths, trying to anchor myself in the present moment. The teacher's stern voice, now softened with concern, penetrated through the haze of panic. "Siah, are you alright? Do you need to see the nurse?"

I nodded slowly, still processing the harrowing events that had unfolded in my mind. "Yes, ma'am, I think I need to go to the infirmary," I replied, my voice trembling slightly.

My best friend gave me a reassuring pat on the back as we made our way out of the classroom. The corridors felt eerily quiet, the usual bustle of students replaced by an uneasy tension. My mind raced with questions, doubts, and the lingering fear of what I had witnessed.
