Dont Go Down There (Short horror story)

I was cleaning my room while my mom was cleaning the bathroom next to me. I looked under my bed to take out old things I didn't want and put them in a box. Once I got done searching under my bed I picked up my box and walked to the bathroom and saw my mother looking at herself blankly in the mirror. I wanted to ask if she was okay, But I will once I get this of this box.

"Mom, where can I put this?" I asked her. She slowly turned to me and a smile suddenly appeared on her face. More like an evil grin.

"Somewhere downstairs, Honey. Just don't put them in the basement."

I wanted to ask, but her temper has been short lately so I didn't bother to ask. I carefully walked downstairs with the box in my hands. I looked around the living room and there were already so many boxes down here. So, I went into the kitchen and tried to find a corner or something.

But one corner had the basement door.

I kept telling myself "Don't go down there, Don't go down there", but curiosity was eating at me slowly with each passing second. Once I couldn't help myself anymore, quietly opened the basement door and made my way down the steps making sure my mom didn't hear me.

As I made my way down the steps, I was surrounded by darkness of the room. I hold the box in one hand and try to look for a light switch with the other. After five minutes of searching, i found a tiny chain on top of the ceiling and pulled it down, making a click sound, then the lights coming on. Right when it came on, the first thing that happened next made everything in my body go cold.

I was looking at my mother, tied up on the floor and her eyes looking at me soullessly. I dropped my boxed and covered my mouth to prevent a petrified scream. I can't believe it. It was my mother, lying there dead on the floor with her eyes wide open. I didn't even want to know what happened to her. And then a thought made my heart drop.

If this is my mother... Then who's the upstairs that looks exactly like her...?

Before I could even think to get out, It was already too late once I felt ice cold breathing on the back of my neck and a distorted whisper that put me in tears, knowing that whatever it was would be the last thing I hear.

"I told you not to come down here, Sweetie."
