I got a call from my mom, asking me to pick up my brother from school. Her voice was tired. I drove there, found him waiting outside, and brought him home. Mom turned pale. She said, ‘But I never called you.’

Turns out she hadn’t called me at all. Her phone was in the kitchen drawer, right where she’d left it that morning before heading to her part-time job at the community center. I pulled out my phone and showed her the call log—8:17 a.m., “Mom” with a two-minute conversation.

She stared at it, confused and a little shaken. “I don’t understand,” she whispered. “I was busy handing out food packs. I haven’t touched my phone all day.”

I looked over at my little brother, Felix, sitting cross-legged on the living room rug, peeling the sticker off his math folder. He looked calm. Normal. Like nothing strange had just happened. But something felt off.

Felix was usually chatty. He’d tell you how his day went, who got in trouble, what he had for lunch, everything. But now, nothing. Not a word. Just that sticker.

“Hey, buddy,” I said, trying to sound casual, “how was school?”

He looked up, met my eyes, and said, “It was fine.” His voice was flat. Not rude, just…empty.

That night, I couldn’t sleep. I kept thinking about the phone call. I replayed the conversation in my head. Mom’s voice—yes, it had sounded like her. But there had been a weird static in the background. I’d brushed it off at the time.

I got up, went into the kitchen, and checked the call log again. Same number, same timestamp. I tried calling it back, but it rang once and then went to voicemail. The voice on the message wasn’t Mom’s. It was a robotic male voice: “The number you are trying to reach is not in service.”

I stood there, heart racing. I knew something was wrong.

The next morning, I decided to ask Felix more questions. I found him already dressed, sitting at the table eating dry cereal out of the box. He never did that. He liked warm toast with butter and honey.

“Hey,” I said. “You feeling okay?”

He nodded without looking at me.

“What did you guys do in class yesterday?”

He shrugged. “Math. Reading. Same stuff.”

“Who’s your teacher again?”

He looked up, then tilted his head, like he was trying to remember. “Uh… Mrs. Carter.”

I froze. Mrs. Carter had retired in June. His new teacher was Mr. Dale. I knew that because I helped him label his notebooks at the start of the school year.

“Are you sure?” I asked.

He blinked at me. “That’s what she said.”

I didn’t argue. But I grabbed my car keys and told Mom I’d be back soon. I drove straight to the school.

Mr. Dale was in his classroom, sipping coffee and grading papers. When I explained the situation, he looked genuinely concerned. “Felix was marked absent yesterday,” he said. “I assumed he was sick.”

I felt cold all over. “He was waiting for me outside the school. Right where the buses line up.”

Mr. Dale frowned. “That’s not possible. We didn’t see him at all. The front office doesn’t have any sign-out record either.”

When I got back in the car, my hands were shaking. I called Mom from the parking lot and asked her to keep Felix in the house, no matter what. I didn’t explain. I just said, “Please trust me.”

That night, I watched Felix like a hawk. He barely ate. Didn’t ask for TV time. Just stared out the window toward the backyard. Around ten, I caught him slipping out the back door.

“Hey!” I called, making him jump. “Where are you going?”

He looked startled, like I’d caught him doing something secret. “Just going outside.”

“At ten at night? With no shoes?”

He looked down at his bare feet, then back at me. “I need to go back.”

“Back where?”

He didn’t answer.

I pulled him inside and locked the door. We sat on the couch, and I made him look me in the eyes. “Felix, what’s going on?”

He bit his lip, looked around the room, then leaned in and whispered, “It wasn’t me.”

I stared. “What do you mean?”

“The boy you brought home yesterday… wasn’t me. It looked like me. But I was still at school. I saw him wave at you from the sidewalk. I tried to shout, but nobody could hear me.”

My stomach twisted. “So where were you?”

“In the old shed by the football field,” he said. “Someone grabbed me. Someone who looked like me.”

That shed had been boarded up for years. I didn’t even think kids went near it. I didn’t know what to believe anymore.

“I only got away because it got distracted,” he continued. “It heard your car and looked toward the gate. I ran and hid in the bushes. Then it walked off… like it was you.”

I blinked. “What do you mean, like it was me?”

“It started walking the way you walk. Had your keys in its hand. Then it turned and smiled at me. But the smile was wrong.”

I took a deep breath. “Then where were you all night?”

“I followed you home. Watched from the woods. I waited until it fell asleep in my room, then climbed in through the laundry window. I’ve been in the attic since then.”

I was trembling now. I didn’t know what part scared me more—that someone or something had taken his place, or that he’d been in the attic all night.

I looked toward the hallway, toward Felix’s room. I told the boy sitting in front of me, “Stay right here.”

I walked slowly, heart pounding, and cracked open his bedroom door.

The bed was empty.

Just neatly made covers, and Felix’s favorite plush bear resting on the pillow.

I turned back to the living room. Felix was gone.

The front door creaked open as I reached it. I sprinted out, barefoot, calling his name. I caught a glimpse of him running toward the woods behind our house. I chased after him.

When I caught up, he was crouched behind the oak tree near the creek. “It’s still here,” he whispered.

“What is?”

“The other me.”

Then I heard it. Leaves crunching. A figure in the distance, walking slowly. I couldn’t see the face, but it had Felix’s size and build. My heart pounded so loud I could barely hear the rustling.

It was humming. A strange, low tune. One I didn’t recognize.

I grabbed Felix’s hand and whispered, “Run.”

We ran for what felt like forever. Back to the house. I locked every window, every door. Pulled the curtains tight.

We didn’t sleep that night. The next morning, I told Mom everything. She didn’t believe it at first. But when I showed her the empty bedroom, and the two bowls of cereal that had been in the sink—she started to.

We took Felix to stay with our aunt three towns over. Somewhere safe. Somewhere without woods or sheds or anything that could watch him.

I spent the next few days digging into local history. There were stories—legends, really—about changelings. Old folk tales passed down by farmers and loggers. Things that took the place of children. They’d copy everything, perfectly. But something always felt off.

Sometimes, people caught on in time. Sometimes, they didn’t.

I went back to the school late one evening, just as the sun was going down. I walked to the old shed.

The door was unlocked.

Inside, it smelled like damp earth and rust. In the corner, I found a school bag. Felix’s name was scribbled inside. There was also a note—childlike handwriting, scrawled on the back of a math worksheet.

It read: “If I don’t come out, don’t take him home.”

I stood there for a long time.

Then I heard the humming again.

It came from behind the shed.

I didn’t wait. I ran.

I didn’t look back.

After that night, things went quiet. No strange calls. No lookalikes. Mom changed her number. I deleted the call log from my phone. I still don’t know what I brought home that day.

But I know what I left behind.

We never talked about it again, not really. Felix stayed with Aunt Vera for months. He started smiling again. Talking like his old self. And when he came home, I made sure never to let him out of my sight.

Years later, when I was in college, I got a call from an unknown number. It was a child’s voice.

It said, “You left me in the dark.”

I hung up immediately.

And I changed my number too.

I guess the twist is that I thought I was helping. That I’d done the right thing. But sometimes, trying to fix things without understanding them first… brings a different kind of danger.

I don’t know what that thing was. But I know this: always trust your gut. If something feels wrong—it probably is.

And sometimes, the scariest part isn’t what’s taken. It’s what comes back in its place.

If this story gave you chills, or made you think twice about the everyday moments we take for granted—share it. Like it. Pass it on.

You never know who else might need the warning.
