The informant is a college student from Reno, Nevada.

This supposed “syndrome” is a piece of online lore which comes from the Pokemon video games for Gameboy. The informant first stumbled upon a website about it while he was in high school. However, he played the games when he was seven or eight years old. In the game, the player travels from town to town, advancing towards the end. One of the towns is called Lavender Town. In it, there is a tower full of ghosts of wandering souls of Pokemon who have been murdered. When the player enters a new area, the music changes. Each town has its own song, and the informant recalls Lavender Town’s being particularly creepy.

This song is central to the lore which has become an online legend. According to the legend, when the first prototypes of the game came out in Japan in February of 1996, there was a spike in illness of children who bought and played the game. These “illnesses” supposedly made them mentally unstably, resulting in a spike in suicides and violent behavior. According to the legend, the high frequencies used in the song resulted in these physiological changes. The informant does not actually believe the legend is actually true, mostly because it is posted on a page called “creepypasta Wiki”, a page for stories that are generally made-up internet hoaxes. Still, there are entire forums filled with lengthy theories about missing frequencies and ghosts in the machine. The following is a link to the song, as heard in the final, U.S. version:
