The King In Yellow

A 19th-century cosmic horror trope that acts as a mental virus. It is a cursed, two-act play that, upon reading, causes immediate obsession, existential dread, and total insanity in the reader. Associated with the mysterious city of Carcosa and the Yellow Sign, the entity acts as a bringer of madness, often interpreted as an avatar of the cosmic deity Hastur.

You should also know the viral Minecraft ARG "Searching For A World That Doesn’t Exist" created by YouTuber Wifies, d3rlord3 is the genius protagonist who gets stalked and eventually "broken" by the one and only King in Yellow.

Friend 1: I just read the second act of that play, and now I’m seeing black stars over the Arby’s parking lot. Pretty sure The King in Yellow is about to pull up.
Friend 2: Are you ok, man?

The feeling of obtaining an informational hazard after seeing or watching something scary.

When I was eight years old, I read the Jeff the Killer creepypasta, and suddenly couldn't bear to go outside in public for like a month due to how scared it made me. Obligatory mention of "King In Yellow Syndrome" so this will get submitted.
