Emily Carter had always considered herself a light sleeper.
So when she woke up shortly after sunrise one morning, something immediately felt unusual.
Her bedroom was quiet, her windows were closed, and everything appeared normal.
Then she looked at her left arm.
There was a strange red mark near her wrist.
It wasn’t a serious injury, but it looked unusual—almost like a perfectly shaped circle pressed against her skin.
Emily couldn’t remember hurting herself before going to bed.
She checked her sheets and the floor beside the bed, but there was nothing that explained it.
Then she noticed something else.
Her bedroom door was open.
Emily always closed the door before going to sleep.
She initially assumed she had simply forgotten.
But the feeling that something wasn’t right stayed with her throughout the morning.

A few months earlier, Emily had installed a small security camera in the hallway outside her bedroom.
