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.
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.
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.

Another thing could be seeing someone with a very strange fashion sense. It makes you wonder about different styles and cultures.
One possibility is that the lights start to flicker. This would add to the already terrifying situation.

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.
