Malfunction could be one. Like when it doesn't stop vibrating or changes its pattern unexpectedly.
Lack of proper user instructions can also contribute. If users don't know how to use or maintain the vibrator correctly, it can lead to issues. For example, using the wrong type of batteries or not cleaning it regularly. This can result in problems like corrosion inside the device, which may cause it to malfunction in unexpected and sometimes scary ways.
Well, perhaps a story could be that someone bought a second - hand vibrator. Little did they know it had some sort of hidden defect. When they used it, it overheated and started to smell like burning plastic. It was really terrifying as they were worried it might catch fire or cause harm to them. They immediately threw it away and learned the hard lesson of not buying second - hand personal items like that.
Ghosts could be a possible element. In 1928, superstition was still quite prevalent, and a horror story might involve the apparition of a vengeful spirit.
Perhaps it's a story about a group of people in a research study. They are given access to vibrator chairs for seven days. Some might use it for relaxation, some for post - workout recovery. The plot could involve their different experiences, from those who love it and feel great benefits, to those who might find it uncomfortable or not effective at all. Throughout the seven days, there could be discussions among the group about their findings, and at the end, a conclusion about the overall effectiveness of the vibrator chair.
One possible element could be a creepy old mansion. It might be abandoned and full of dark corners where strange things happen.
The waiter himself could be a key element. He might have a past he doesn't remember, which is somehow related to the horror. For example, he could have been involved in a murder at the restaurant in a past life, and now the spirits are coming back to haunt him. Also, the customers could be strange, like they are not really human but some sort of otherworldly beings just pretending to be normal diners.
One possible element is the sudden and terrifying hallucinations. People on bad 'ecstasy' might see grotesque monsters or distorted versions of people around them.
The Detroit Horror Story may contain elements such as the isolation of certain neighborhoods. These areas, cut off from the rest of the city, can feel like a world of their own, full of mystery and danger. The presence of graffiti - covered walls and broken streetlights can add to the spooky atmosphere. There could also be elements related to the city's history of racial tensions, which could manifest in stories of hauntings or vengeful spirits.
One possible element could be the use of his unique musical sounds as a trigger for the horror. His music often has intense and somewhat otherworldly beats that could be associated with something sinister.
