69 Bizarre, Creepy, And Terrifying Incidents From The World Of Overnight Jobs

The night shift is often called the graveyard shift — because of the quiet, eerie atmosphere, and a kind of working-alone-in-a-cemetery vibe.

Even horror movies tap into that exact same vibe — linking darkness to mischief, spirits, and general unease.

It’s no wonder then that our brains unknowingly associate the dark with supernatural or scary activities.

Research shows that low lighting can trigger feelings of insecurity or anxiety because the brain assumes there could be danger nearby. On the other hand, brighter spaces tend to make people feel safer.

Recent research shows that about 14.2% of employed US adults work overnight hours — typically defined as between 1 am and 5 am. That translates to more than 21 million Americans being regularly awake and working while most of the country sleeps.

Studies say that our brain is already hyper-alert at night.

Even a flickering monitor, a squeaky hallway, or a stray raccoon in the parking lot can look like the opening scene to a horror movie.

Darkness and fatigue also heighten senses that you barely use during the day, such as your fear responses.

Small noises seem louder and shadows may seem to move. Shapes in your peripheral vision may suddenly look like some lurking figure.

If you’re sleep-deprived — which night shift workers often are — your brain’s logical reasoning takes a little nap of its own.

People who work through the night usually report higher levels of stress and anxiety, which can make their experiences feel extra eerie.

Their cortisol levels are higher and being alone, or with less people, at night can also make them see danger in totally normal things.

Recent research from the EU showed that 51% of people working night shifts had at least one sleep disorder, which was strongly linked with increased stress, poor mood, and mental health problems.

“Because those working night shift will remain de-synchronized with the day-work focused environment they live in, it is unlikely to completely prevent all negative consequences of night work,” says Dr Marike Lancel, a researcher at GGZ Drenthe’s Mental Health Institute.

Even architecture can play tricks on your mind.

Long hallways, huge buildings (think brutalist architecture), echoing rooms, staircases disappearing into the dark — all of these things can feel potentially dangerous.

And if you’ve recently watched a horror show, your brain might try to fill in the gaps with stories and shadows that aren’t really there.

Experts say these sensations aren’t superstition but the brain misreading its surroundings.

A faint smell of dampness or dust — like in old hotels, castles or even hospitals — tells the brain this isn’t a place meant for comfort.

Buildings that once stood tall but are now falling apart can also make people think about the stories behind them. Like who once lived there, or what might have happened before everything was left to decay.

“This narrative vacuum, coupled with visual uncertainty, stimulates the brain’s default mode network, the same system used for imagination and memory, giving the space an almost haunted quality. Your brain tells itself stories to make sense of the ruin, and those stories tend to skew toward danger or loss,” says Beth Tauke, associate professor of architecture at the University at Buffalo.

Another major reason people feel more uneasy at night comes down to safety.

Fewer people on the streets and in workplaces, less light, and quiet surroundings can create more opportunity for society/">crime or harassment.

A recent report from the UK said night workers may be more exposed to violence or harassment than day workers, partly due to less staff members and less supervisory support overnight.
