15 - Babysitter

-A story about a girl asked to babysit some kids - she sent them to bed around 9pm and went off to do her own thing watching TV and getting some homework done

-From inside the basement she heard rustling and pans falling over - instead of going down to check, she phones the police and informs them there might be someone down there

-Instead of a single patrolmen turning up at the house, an entire SWAT team breaks in and searches the basement only to find a man who happened to be wanted for multiple cases of rape in the area - citing they heard someone listening in to her police phone call

-Since he and his wife share custody of his daughter, one some weeks she stays with her mother, and others her father - one particular week in the middle of the night, the father is on the computer

-Out of the corner of his eye he catches his daughter sneaking into the kitchen, where she stops dead and stares at him for a few minutes but he doesn't look at her since he figured she'd just go back to bed

13 - Hunter

-This one father has a son aged about 4 or 5 called Hunter - when he gets bad dreams, he'll climb into his parents bed

4 - Hidden Door

-A girl living with her grandmother and aunty, when they heard strange noises coming from inside the walls at night

-Figuring they might be rats, her grandma moved some furniture that had come with the building only to find a suspicious piece of plywood which, when torn off, revealed a tiny child-sized door

2 - Alien

-A man waiting for his wife one night on the weekend, washing dishes when the motion-sensor light on the back patio lit up

-He grabbed a knife and peeked through the curtains on his door to see a grey creature squatting on the ground just out of the light's reach, rocking back and forth - and as he stared at it, the creature stood up fully

-What he saw on the creature's face made him jump back in terror - giant red eyes too big for its face, featureless and expressionless

-It approached the door, the man screamed at it, the lights went off and the creature vanished - he scoped out the backyard but he never saw it again

-He saw a girl that looked similar to my sister, a bit younger than her standing next to my mother's sleeping body, staring down at her looking extremely sad

-My Dad called her name, but she didn't respond, and that's when my Dad realised it wasn't her - she ran out the room, he gave chase but she vanished into the hallways - he checked on my sister but she was still asleep

-He swore to his dying day that she looked exactly like another daughter of his might look - staring down at my mother for who knows what reason.
