Liminal Spaces

Then there are the Buck Rooms.
If people stay in them too long, they turn into ponies and are dropped into Equestria with no memory of their previous lives spent as a human.
Well, except for Lyra, she talks about humans because she still has vague memories of being one.

Now, I want to hear about the Front Rooms.
You know, places that are the direct opposite of the Backrooms.
A place with violet wallpaper and throngs of faceless people in wide rooms.
The carpet is covered in dust and the lights are few.
There is no monster chasing you but every time someone from the crowd bumps into you, something is lost.

Hmm, this might make an interesting story.
