feral hobos who wandered into this strange realm and never found a way out. literal molemen. giant worms. sentient colonies of insects and/or rats. spiders in every shape and size. strange fungi.

There's a tribal society in Metro 2034 that believe the tunnels were dug out by giant worms. They worship said worms and also sacrifice people to them. The leader of the tribe was able to practice a form of hypnosis.

I'm trying to remember the name of a short story I read about a guy who accidentally crossed into another dimension on a subway, and when he tried to get back to our reality, he ended up in yet another reality, and realized he was probably never getting back to Earth.
I think it might have been a Stephen King short. Anybody know what I'm talking about?

I've read a lot of Steven King and it's not ringing any bells. Clive Barker maybe?

>Sometimes the PCs will see trains that pass, but always pass whatever platform (I mean, they'd be abandoned anyway) they're on, and they don't look too friendly anyway. among these include:
>A rusted, old train from an earlier time, it seems in as bad shape as a train that old should be, if the PCs are able to make a successful spot check, they might see some familiar faces aboard belonging to people they know are passed on
>A modern train, but this one passes with no one inside. No passengers, no driver, nothing. But screaming can be heard inside
>some of the Feral Hobos have degenerated to the point of looking outright like zombies
>some, may in fact, be certainly operating in a way humans should not survive either.
