the sliding shadow

A creature the size of an average adult, completely dark and black, hairless, with smooth skin, its eyes are the only thing visible in the darkness, it has claws, and its feet slide, but in rough areas it tears its feet.

Is the creature male? And its race, could it be demonic or ghostly?

On that quiet street in an old neighborhood, the early mornings had a different weight to them. It wasn't just the wind rustling through the wires or the creaking of wood in the old houses. It was as if something was awake when everyone else was finally asleep.
They said the Black Shadow made no sound. It had no footsteps, no breath. It simply… was there.
It always started the same way: someone would wake up in the middle of the night, without knowing why. The room seemed normal—the door closed, the window ajar, the fan spinning slowly. But there was a strange feeling, as if the air were colder. Heavier.
And then came the certainty: someone was watching.
In the corner of the room, where the streetlights barely reached, the darkness seemed denser. It wasn't just a lack of light. It was as if the shadow itself had a form—tall, elongated, still. Faceless. No visible eyes. But whoever saw it knew they were being stared at.
The Black Shadow didn't approach immediately. It stood there, motionless, for minutes that felt like hours. People tried to scream, but no sound came out. They tried to move, but their bodies wouldn't respond. They could only breathe rapidly, feeling their hearts pounding in their chests like a desperate drum.
And then, when the fear reached its peak... she moved.
He wasn't walking. He was gliding.
Slow.
Silent.
He would stop beside the bed, leaning slightly over whoever was sleeping. And just when it seemed like something terrible was about to happen…
The alarm clock was ringing.
Morning.
Light is coming in through the window.
And the room was empty.
But the stories began to repeat themselves. Neighbors commented at the market that they too felt something at night. Children said they saw "a man made of night" standing in the corner of their room. One man swore he woke up and saw his own shadow on the wall move... even though he wasn't moving.
The strangest part?
The Shadow never touched anyone. It never left marks. It never did harm directly.
She just watched.
And the more someone talked about her, the more frequent the visits became.
