A Demon Maybe ?
It was a weird lonely night and the house was empty ,our house is three floors hight its a victorian style house big and empty and scary at night . I was going from the first floor to the third , at the second floor like in front of it there is a hallway with the elevator at the end of it . that hallway is always dark and freaky the elevators door or thing what ever has at mirror on it and at the corner i saw something black just like a black shadow and it was moving so i ran up the stairs quickly . i saw it again the next day .
