Nightmare Fuel / Vsauce

• The "Why Are Things Creepy?" video from the main channel is understandably nightmarish. It incorporates a surprising amount of horror tropes to top. You might not be able to watch all of it the first time through.
  • What's even more scary is that at the start of the video, you can see somebody in the back behind Michael... and it's never brought up again. Not to mention that the video has a purposefully-done grainy texture, like something from a story about a haunted VHS tape.
    • it's hard to notice, but just as Michael is about to block the person's line of sight, the person fades away.
  • Not to forget the face in the very last seconds of the video. You may not see it instantly.
    • During the video, items are switched and replaced on the shelves. It's difficult to catch, but the mind might subconsciously realize that something is being changed and doesn't feel right. As Michael said, the creeps related to the uncanny valley is coming home and realizing everything in your house has been replaced with an exact copy.

• In the video "What Does Human Taste Like?", there's a shot of Michael's severed face (well, more like the entire front of his skull) plastic wrapped and served up like a cut of meat from the butcher's. Better yet? It's the thumbnail for the video, so you can't avoid seeing it.
  • The video in general, really. Complete with examples of people who ate other humans to boot.

• In the video "If" we get to see an imitation of what would happen if the U.S. was under a nuclear attack that could be very disturbing to someone living in the U.S. In the same video, we learn that there was a strong possibility that the first two men on the moon might have been stranded there and would've been forced to commit suicide or starve to death.

• The video "Cruel Bombs" is about nuclear weaponry. In it, we not only learn that there was almost a gulf in the United States after a nuclear warhead barely avoided a nuclear accident, but that the odds of a similar accident happening in the future are, relatively speaking, very, very high.

• In the video, "What If The Earth Stopped Spinning?", there's a brief animation just that, featuring buildings being abruptly torn from their foundations and dozens of people being flung through the air at over a thousand miles an hour, flopping like rag dolls.

• In Jake's video "3 Time Travel Paradoxes" he accidentally kills himself in the past, erasing himself from existence.

• Jake's video "Could You Survive a Fallout?" takes place literally Just Before the End, and comes to the conclusion that "The question isn't IF you could survive a fallout...it's whether you'd want to."

• In the video about ghosts, there's a Jump Scare with a stuffed deer head that is briefly possessed. While it is used for comedic effect, it can be quite startling to first-time viewers.

• In Jake's video "Could You Be A Parasite?" The idea that if one were to be infected by a parasite we would possibly never be aware of it. This is exemplified in the ending, did Jake stay so that others won't be infected or was he infected with the parasite?

• In Jake's other video "Is THIS The Deadliest Pokémon?", it opens with Jake standing in a strange place. Jake mentions that across all of the creatures he has come to know, one of them was far scarier than anything else he encountered: #122, Mr. Mime. A flashback ensues; it is now 4 months ago in the City of London. There, he explains that its ability is simple: by vibrating its fingertips an invisible wall can be created which stops molecules. This doesn't sound too bad....until you realize that, well, this is Vsauce. Jake explains that to do this act IRL, you have to lower the molecules down to a temperature that has never been witnessed: absolute zero - 0 degrees Kelvin. He then goes on and elaborates on the ramifications on extremely cold temperature: things such as superfluids: fluids which have no viscosity. But it gets worse, for if you go lower than even that you begin to witness something called a Bose-Einstein Condensate; when matter coalesces into a single quantum wave. Eventually, he sums up how the Pokemon kills you: By instantaneously dropping the temperature of your body to absolute zero (thus causing its zero-point energy to become apparent), it effectively becomes an invisible quantum system of matter for as long as its fingers sustain the actions...which means for that duration, you effectively become nothing. The instant he lets go, the system breaks, allowing photons to excite your molecules...but in doing so, you are disassembled on a quantum level.

• In Mind Field, the "What is the scariest thing out there?" episode is probably the most terrifying. The fact that it is filmed like an old horror movie, complete with all the cliches, doesn't help.

• His What if the sun disappeared video is about Exactly What It Says on the Tin. If it did happen, almost everything on Earth would be dead within a year. People in sufficiently sheltered places could survive longer, but would still likely eventually freeze, as the air itself would eventually get so cold it turns into deadly freezing liquid.

• Kevin's series on the abuse of mathematics by law enforcement gives a strong sense of Realism-Induced Horror. Police neglect actual harm to individuals and society to keep the weekly statistics of vandalism or jaywalking low based on questionable gathering methods and perverse incentives, arbitrarily decided probabilities being used to sentence someone for decades, and proprietary black box formulas rating a black teenage girl who steals a scooter to joyride it as a higher recidivism risk than a middle-aged white man who has committed multiple violent crimes. Dressing prejudice as science is nothing new, but the sheer amount of paper and data that can be used to make it look scientific is legitimately frightening, due process being undermined, and the supreme court not caring about the issue at all.
