Inspired by @Just A Interesting Dog Here. Let's go:
I am God: This is very long, but I'll try to summarize it: Good old 4chan, friend of an user gets a "virus" in his pc, strange things in his house happen too, strange coded archives, they try to decode and find this (warning, may be a bit disturbing): photo.
Some users in the thread also reported the photo in their pc's and strange texts too. A video also shows a face similar to the "God" photo that was decoded. Some speculate that it was an edited photo of Dylan Klebold (One of the Columbine sh00ters).
Kanye Quest 3030: A very cool JRPG made in 2013. A fictional Kanye West travels through dimensions, finds clones of other rappers and rap battle via turns. 2 whole years later, a person finds a secret ending.
It started with an interaction saying "ASCEND and worship The Based God". An NPC asks what you want to do. He types "ASCEND", game "ends". Guy datamines the archive, finds secret passwords, goes through hallways, one of them just turns into a blank screen.
Game asks you for your name and address, nothing happens after. It looks a lot like a bad creepypasta, I know.
Lavender Town Syndrome: Lavender Town was a town in Pokemon Red & Green. Apparently, the original Lavender Town music was causing from migraines to non-alive in extreme cases, specifically in kids between 7-12.
This mostly affected people that played with headphones. Soon after, Nintendo released a version with mono audio and lower frequency. Was this 100% real? Probably not.
The Backrooms: Well...
Fatal Insomnia: Ricard Siagian was a normal Indonesian man that moved to the USA. He got an UTI and took an antibiotic with a lot of side effects, including disability and damage to the nerves connecting the brain and the spinal cord to the body.
Sadly, he probably experienced the last one, causing extreme insomnia. A doctor prescribed sedatives, and it worked. For some months. We went without sleep for four whole months. He documented his progression on Youtube, and eventually a doctor in Beijing talked to him to get a treatment.
He raised a gofundme page, but sadly didn't reach his goal. He passed away in 2016. My heart goes out to his son and his family.
