I saw something impossible in middle school and I still can't explain it

So this is gonna sound insane but when I was in 8th grade I was literally seeing things. Like when I'd be on the computer someone would slowly walk past me in my peripheral. When I'd be doing dishes I'd catch someone poking their head around the corner staring at me. White smoke floating around. ㅋㅋ And one time I was washing my hair and got this weird feeling so I glanced at the bathroom door (it was that frosted glass type) and I SAW something. Like a mannequin head from a wig shop sitting on top of the toilet. With hair all wrapped around it. Scissors kept falling. It was BRUTAL.

Obviously I was probably just seeing shit but like. This one thing. I still have no idea what that was.

Okay so this was during the Buddy Buddy era (RIP) and my friend and I were swapping scary stories. She told me something that happened to her a few days before. Her family runs a supermarket so her parents get home late. It was just her, her cousin (older girl), and her little brother at home. My friend was gaming in her room, brother was sleeping in the master bedroom, cousin went out.

Around 10pm someone starts knocking on the front door. My friend's like "who is it?" NOTHING. Then BANG BANG BANG BANG like actually violent knocking. She gets pissed and yells "WHO THE HELL ARE YOU?!" and the person keeps pounding while CALLING HER BY NAME. Like if her name was Kim Bailey it's "YO KIM BAILEY OPEN THE DOOR!! HEY YOU HEARING ME?!" It sounds exactly like her cousin.

So my friend goes to open it. Door swings open. Nobody there. NOBODY. Her place is a villa so there's sensor lights in the entryway right. They would've triggered. And even if someone was pranking her the floor below would light up too and she'd hear footsteps on the stairs. She heard NOTHING. She even went up to the roof to check. Empty.

But she's 100% sure it was her cousin's voice.

So she just locks up and goes back to gaming. Then at midnight her cousin actually shows up. My friend asks "why'd you come by earlier and leave?" and the cousin looks at her like she's completely unhinged. "Do I look that bored to you? I've been in Seoul this whole time. Just drove back now."

So we're in Buddy Buddy talking about this and I'm genuinely getting the creeps. Like I don't even know why but something about that story made me SO nervous. And then. THEN.

Someone POUNDS on MY front door.

"YO [MY NAME] OPEN THE DOOR!!"

I literally thought my heart was gonna explode. I RAN to the door and yanked it open. Nothing. Nobody. NOTHING.

It was like 8pm. My brother didn't get home from cram school until 10.

I was so freaked out I literally ran barefoot to check the gate, the neighboring alley, EVERYTHING. Didn't look like anyone had snuck in or left. I was TERRIFIED waiting those 2 hours for my brother.

What the FUCK was that. Why did I experience the exact same thing my friend just told me about. I still don't understand it. That 2-hour wait was actually horrifying.

Now I'm scared if I tell anyone else that thing will come for them too but honestly I needed to get it out. It sounded like my brother. He said my name. Knocked on the door. But when I opened it...

I'm never getting an explanation for this am I.
