Kind of a weird semiotics misunderstanding. There was this trashy tabloid news program that did sensationalised nonsense most of the time, and they advertised the show with these teasers that were like, "tune in for the shocking conclusion OMG SO DRAMATIC", it was ridiculous.

One time they were talking about a security guard who was killed, and the ad had some footage of the incident - or a reenactment -shown in slow motion with a red filter. The implication was you were seeing real footage of a lethal encounter, and OMG SO DRAMATIC.

Then later that week they were doing a piece on school bullying, and they had what was probably actors where two kids walk past each other in the halls and bump shoulders, you know, like you'd do in a TV show as shorthand for bullying. They put the same slo-mo red filter over it, and the same ominous DUN DUN soundtrack OMG SO DRAMATIC.

I thought that red slo-mo filter meant death, so I thought I was watching security camera footage of the lead up to an incident where one kid literally killed another kid. It was pretty traumatic.

I'm glad I didn't grow up on a diet of that, I just saw the ads and didn't like it. This is how people grow up to be afraid of everything they're told to be afraid of.
