I'm not sure specifically about R and R Trucking in Lodi, CA horror stories. But generally, in the trucking industry, horror stories could involve things like bad road conditions causing accidents. Maybe there were issues with the trucks breaking down in remote areas, leaving the drivers stranded for long hours. Or perhaps there were problems with management not treating the drivers fairly, like making them work overly long hours without proper breaks.
The unknown is often the scariest. For example, in many stories, there are unexplained noises or apparitions. You don't know what's causing them or what they might do.
In another antimlm horror story, an individual was lured by the flashy presentations of an MLM. They were told they could achieve financial freedom easily. But as they dug deeper, they realized the company was just using new recruits' money to pay the old ones. When they tried to leave, they faced threats and harassment from the upline members, which was a truly terrifying experience.
At a r convention I heard of, the special guests didn't show up as promised. Fans had paid a lot of money to see them, and there was no prior notice. Everyone was disappointed and angry. They had planned their whole day around meeting those guests, and it all fell apart. It was a nightmare for the attendees who were really looking forward to that experience.
Another theme is the loss of sanity. Characters often start off normal but as the horror unfolds, they lose their grip on reality. For example, in 'The Shining', Jack Torrance slowly descends into madness as the haunted hotel gets to him. It makes the readers question what is real and what is in the character's deranged mind.
One horror story is about a girl who met a guy on Tinder. He seemed nice at first, but when they met in person, he was extremely possessive. He started checking her phone and didn't want her to talk to other people. She quickly ended the date and blocked him.
