It’s one of those lore things, like the SCP Foundation or any folk tales, this one just happened to come from 4chan.

The idea of liminal spaces being creepy or unnerving isn’t new, the cumulative lore around an example of that is where you get this particular story.

The SCP Foundation is another good example of this.

Is it full nerd to read through fictional files on pretend beings, sure.

Is it enjoyable, also yes, for a particular subset of people.

The reason I think this is a good example is because this particular aggregate folk tale is bleeding into other projects.

The game Control has strong SCP vibes, as does abiotic factor.

You’ve also got niche stories like "There is no antimemetics division"

Here is a short (15 min) film covering the opening of that book

Spoilers obviously
