10 Most Unnerving Short Horror Stories On The Internet

National Parks are beautiful places of refuge from the unending drone of society. This chilling NoSleep entry puts out the unsettling idea of that refuge being ground zero for indescribable terror.

A National Park Ranger delivers their first-hand account detailing some strange happenings at his job. As he tells his story, the mystery of what horrors lurk in the shadows remains hidden behind a shroud of secrecy. The ranger, and by extension the reader, have no idea what is going on, just that whatever it is cannot be allowed to spread.

The ambiguity at the heart of this story is what makes it so frightening. Sometimes, ambiguity can be used as a cheap trick as to not have to come up with any definite explanation. That is not the case here. Much like several other entries on this list, it's the not knowing that will scare you the most.

It reads almost like a cosmic horror tale in the way those who have seen this unknown threat go insane just by looking at it. Their rational thinking becomes corrupted as the urge to destroy it overtakes them, yet nothing short of napalm will do the trick. What's even worse, the very defenses that have been set up to fight this thing seem to have the complete opposite effect.

An unspeakable evil, a mysterious government organization, and secrets galore. What more does a good horror story need?
