Though the door

 Mary doesn't want to be some creeps fuck pet so using the last of her will she runs for the open door.  Once inside she slams the door shut and leans against it gapsing for breath and finding the cat side sleeping at the moment.  

"I'm me again.  I better get out of this stupid costume before what ever caused me to act like a cat starts up aga...."   Mary had stopped talking when she saw that she was right back where she had started.  Though now instead of seven maniquines there seems to be hundreds all wearing every possible costume one could imagine and some that seem so impossible she almost thinks that she is dreaming.

"Thats it!  This is all some strange dream.  None of this can be real."  With that thought in mind she sighs with relief and walks down the stairs to the costumes.

"Well I never had such a realistic dream before.  I might as well have some fun and try on other costumes after all if I don't like one I can just come back and put on another.
