Recently saw an old video of Adam Lanza (school shooter) playing dance dance revolution really well. I had seen it forever ago but recently stumbled on it again. Without context it’s just some skinny kid crushing it at DDR. But, with hindsight its one of the most uncomfortable videos to watch I can think of. So, media of any kind that isn’t inherently a problem but with additional context becomes freaky.
Crime zone has a whole series on exactly this. Some innocent looking footage like a guy closing his garage door, and then with further context it takes on a whole different meaning.
