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.
