Last week, I got a letter from my grandma telling me never to visit her again. It hit me like a ton of bricks because my grandma raised me and my sisters after our mom died when I was 11.

At first, I thought it was a joke. I called my sisters — turns out they got the same letter. Grandma’s health had been declining, but we still visited weekly. None of this made sense. She was always loving. Always kind.

So I drove to her house.

When I got there, my stomach dropped — the locks had indeed been changed. I knocked. No answer. The curtains were drawn, the house unusually dark. Something felt wrong. I waited… and then decided to watch from across the street.

Half an hour later, a young woman approached the door, unlocked it, and stepped inside like she lived there. My pulse quickened. I rushed to the porch, heart pounding, and pushed the door open behind her.

The house was quiet. Different. The cozy smell of cinnamon and lavender was gone. The family photos had been taken down. Everything felt colder, unfamiliar.

In the kitchen, I found her. The woman. She was pale, mid-thirties maybe, putting groceries into Grandma’s fridge like she belonged there.

“Excuse me,” I said, trying to keep my voice calm. “Who are you?”

She didn’t flinch. Just turned and looked at me with eyes that were sharp and oddly familiar. “You shouldn’t be here,” she said simply.

“I’m her granddaughter,” I replied. “Where is she? What’s going on?”

“She asked me to stay here. To look after the house. She left.”

My chest tightened. “She’s sick. She wouldn’t just leave.”

“She did,” the woman said. “She said it was the only way to keep you safe.”

From what?

She handed me another envelope. My name was written on it in Grandma’s unmistakable handwriting. I opened it slowly.

My darling,
Please understand this is for your own safety. Do not return. Do not ask questions. I’ve done something I cannot undo, and I refuse to endanger the people I love most.
I will always love you. But this is goodbye.
— Grandma

The room spun. “What did she do?” I asked.

“She didn’t want you to find out,” the woman replied. “But you’re here now. You might as well see.”

She led me down the hall to the guest room. The door creaked open. Inside, the curtains were drawn tight. Machines beeped softly. My grandmother lay on a strange bed, wires attached to her temples. Her breathing was shallow but steady.

A machine beside her pulsed with a low hum, glowing with symbols — ancient ones, not just letters, but shifting carvings that seemed to move when I wasn’t looking.

“She’s not unconscious,” the woman whispered. “She’s holding something in place. Something that can’t be allowed to wake.”

A chill moved through me. “What is she holding?”

The woman pointed to the floor. “It’s beneath this house. A seal. And it’s tied to her bloodline. She’s the last one strong enough to keep it locked.”

I didn’t want to believe her — but I remembered things. Strange things from childhood. Whispers in the vents. The way the floor would creak, long and low, even when no one was walking.

“She left notes,” the woman said. “A book. Over there.”

I opened the worn book and read her handwriting:

There is something beneath the floor of this house. Something ancient. It does not breathe, but it waits. And it listens. Each generation, one of us binds it. We don’t fight it — we lull it back to sleep. I’ve heard it speak. I’ve seen it move.

It must never be unbound.

Suddenly, a low rumble echoed through the walls. A shudder. Subtle… but wrong. The woman grabbed my arm.

“We need to leave. Now.”

I looked at Grandma one last time. Peaceful. Still. Dreaming.

Outside, I could feel it — the air around the house was thicker. Like the earth itself was holding its breath.

That night, back at home, a letter appeared on my windowsill. No stamp. No handwriting.

Just a typed note:

The seal weakens when you dream of her.

And that night… I did.

She stood in the basement, whispering softly to the floor. Behind her, something stirred in the shadows. Something old. Something listening.

And in the dream, she turned to me and whispered:

“Whatever you do… don’t come back.”
