One of the best sleepover scary stories is 'The Red Room'. It's about a person who decides to spend the night in a supposedly haunted red room. As the night falls, strange noises start to come from the corners of the room. The temperature drops suddenly, and the person feels an unseen presence. Shadows seem to move on their own, and every time they try to look directly at the source of the movement, there's nothing there. It builds up a great sense of dread and mystery.
One appropriate scary story could be 'The Haunted Doll'. It's about a doll that moves on its own at night. A girl named Emily found an old doll in the attic. Every night, she would hear strange noises coming from the doll's room. When she checked, the doll was in different positions each time. It was really creepy but not too extreme for a sleepover.
One story is about a girl who heard strange scratching noises on the window at her sleepover. Every time she looked, there was nothing there. But the scratching got louder and closer. Eventually, she saw a pair of red eyes in the darkness outside. She was so terrified that she hid under the covers until morning. When she told her friends in the morning, they just thought she had a bad dream.
One scary sleepover story could be about a haunted doll. A group of friends at a sleepover found an old doll in the attic. During the night, they heard strange giggling coming from the doll. When they looked at it, its eyes seemed to follow them around the room. They were so scared that they locked the doll in a closet, but the giggling continued until morning.
Here's another. At a sleepover in a cabin in the woods, the friends heard strange scratching noises on the window all night. One brave friend peeked outside and saw a pair of red eyes staring back at him. He quickly pulled back the curtain. Then they heard something climbing on the roof. They huddled together in fear until morning, not knowing what was outside trying to get in.
There's the story of 'The Vanishing Friend'. During a sleepover, the reader and friends are chatting and having fun. Suddenly, one of their friends disappears without a trace. They search the whole house - under the beds, in the closets. As they continue to look, they start to notice that things are moving on their own. Pictures on the wall turn upside down, and doors open and close by themselves. Then, they find a note written in what seems like blood that says 'You're next'.
The unknown is a big factor. When strange things happen during a sleepover like unexplained noises or objects moving on their own, it's terrifying because you don't know what's causing it.
One not - really - scary ghost story could be about a friendly ghost who just wants to play music. He haunts an old music store and at night, he plays the piano softly. People who pass by the store sometimes hear the music and think it's a CD playing, but it's actually the ghost.
One time at a sleepover, we decided to play with an old Ouija board we found in the attic. As soon as we started, the room got really cold. The planchette started moving on its own, spelling out words that didn't make sense at first. But then it spelled out a name none of us knew. It was so creepy that we quickly put the board away and didn't sleep much that night.
There's a story about a sleepover in a cabin in the woods. The friends heard howling outside all night. They thought it was just wolves at first. But then they saw a pair of glowing eyes peering in through the window. They tried to barricade the door, but the howling and the eyes kept them up all night in a state of pure terror. They were so relieved when daybreak came and they could leave the spooky cabin.
