Its her imagination because she thinks its the other june
In The Story The Tuesday Of The Other June By Norma Fox Mazer What Causes The Sound Of Foot Steps Slowly Creeping Up The Stairs In The Middle Of The Night That June Hears?
It was nothing but her imagination of thieves and robbers.
Wind
Stuff
Its her imagination
What had caused the sounds of someone running up and dow the steps slowly was well at first it was robbers then it was the other goon
It was just her imagination It even said "I DREAM of robbers and thieves climbing up my stairs"
"robbers"
Foot steps
A robber
Zombies, witches or pirates
She's a nut-job
