The window writing prompt

This is my writing prompt it is not from school but a task from school enjoy!

There was something not quite right about the window.

There once was a girl named Ganessa, She was now in her teenage years but growing up she realized something was not right about her home.
Let me explain basically when she was very young, about 5 or 6 her sibling\brother,Coa was playing with a soccer ball but with out thinking he kicked and it aimed straight at the window noticing his mistake he never spoke a word or he would get in trouble but that's what he was thinking on his point of view.
When his mother came dashing into the living room because she thought some one got hurt but instead noticing the window and seeing her son upset she smiled and gave him a cuddle,
"It will be okay, accidents happen and they get fixed"
The next day they got window replacements.
And that you have it is what happened.. But back to the point she always felt so strange around the window. Whatever she had done near that window from walking past to reading a book it was never normal.
She would always feel a shiver of cold or something or some one slowly appearing into the thick block of glass.
She ignored it as she thought she was just dreaming about silly things.
"Dinner time! We got some nice chicken and ice cream for dessert!"
That was her mom calling out to her brother and her self.
As Ganessa walked past like always she looked into the reflection in the window and it said her name!
"Huh,Is that my name! I must be dreaming,"
So she pinched herself
"Ow!okay I am not dreaming"
But as she blinked the name, her name was gone...
