Strange noises are often part of it. Maybe the sound of chains dragging on the ground or a low, guttural growl that seems to come from nowhere. Another spooky thing could be cursed objects. Like a doll found in the backyard that brings bad luck and strange events start to occur once it's been unearthed.
Well, there could be a portal to another dimension in the backyard. A character might accidentally stumble upon it and start to see things from a different world overlapping with our own. For instance, seeing old - fashioned people going about their business in the backyard as if they were still living in their time. This would be really terrifying as it blurs the lines between the real world and the unknown.
Getting stuck between floors with no way to call for help. And then feeling a presence in the elevator with you. Maybe a cold touch on your skin or a breath on the back of your neck. You're trapped in a small space and there's something menacing sharing that space with you. It's a very claustrophobic and terrifying situation.
There could be a strange fog that descends on NH 66. Inside this fog, you might hear voices calling your name. And if you try to follow the voices, you could end up getting lost in the middle of nowhere, surrounded by an otherworldly silence and a sense of impending doom.
A trunk full of old clothes that belonged to someone who died in the house long ago. When you touch the clothes, you can feel a strange coldness seeping through your fingers.
Strange noises like unexplained screams or growls that echo throughout the empty stadium. Also, there could be a sense of being watched even when no one else is around. Maybe cold spots in certain areas that give an otherworldly feeling, as if something from another realm is present.
In Hartfeld, there could be a series of disappearances that are unexplained. People would just vanish without a trace. One by one, the townsfolk would start to suspect that there's something evil lurking in the shadows. Maybe there's a hidden underground tunnel system in Hartfeld, and in those tunnels, there are dark entities that prey on those who are unlucky enough to stumble upon the entrance. And during a full moon, the animals in Hartfeld would act strangely. The dogs would howl continuously, and the cats would hiss as if they could sense something sinister approaching.
Ghostly apparitions are a common spooky thing. Just like in the story where a person saw a figure at the foot of the bed. Another is strange noises, like the scratching on the walls or the whispers. These noises can make you feel really uneasy and scared.
Things like objects moving on their own. For example, a toy that suddenly rolls across the floor without any explanation. Or lights flickering for no reason, which is really creepy.
A teacher could see a ghostly figure of a former student in the classroom where that student used to sit. Maybe the figure would be repeating the same actions as when they were alive, like constantly trying to write in a notebook that was never filled.
One spooky thing could be seeing a strange face that doesn't belong to anyone in the elevator. Maybe it's a distorted face with hollow eyes and a wide, menacing grin. Another could be that your reflection starts to move independently, like it has a life of its own. For example, it might start to wave at you in a very eerie way.
The campfire at Camp Adair might be a source of horror. Instead of providing warmth and a cozy feeling, the flames could start to form menacing shapes, like the face of a long - dead camper. And as the campers watch in horror, the shapes start to move and reach out towards them.
