Post some Creepypasta!
Those are just to start off. Not really scary... I'll look for good ones.

My cousin and I had gone to San Antonio, and we had heard rumors of some haunted railroad tracks. The story was, a school bus full of children had stalled on these tracks with a train coming. The train was going too fast for there to be time to get the children off. So they all died. When we finally found the tracks, we stopped the car, parking it right on the railroad tracks. We were both a little nervous, and scared, and waited for something to happen. Just when we were about to leave, the car started rolling. We were both too freaked out to do any more than grab each other and gasp, eyes wide, mouths open. After what seemed like an eternity, (but was actually less than five minutes tops) the car stopped rolling. We looked around, and we were off the railroad tracks.
Now, that may not seem spooky, but what we saw next scared us enough to jump back in the car and make the six hour trip home THAT NIGHT. Both of us got out of the car and walked around to the back. After the first six hour drive, our car had accumulated quite a bit of dust on it. That's not scary, no. But what was scary was the little sets of handprints all over the back of the car. All the size of children's hands
A young girl is left home alone with only her dog to protect her. When night approaches, she locks all the doors and tries to lock all the windows but one won't close.
She decides to leave it unlocked and goes to bed. Her dog takes its customary place under her bed.
In the deep of night she awakens to a dripping sound coming from the bathroom. The girl is too scared to go check so she reaches her hand under the bed. She feels a reassuring lick from her dog and falls back to sleep. She reawakens to the dripping sound, reaches her hand down to the dog where she feels the reassuring lick and falls back to sleep. Once more she awakens to the dripping sound. She reaches her hand down and feels the lick of her dog.
Now curious about the dripping sound, she gets up and slowly walks towards the bathroom, the dripping sound getting louder as she approaches. She reaches the bathroom and turns on the light. She is greeted by a horrific sight; hanging from the shower nozzle is her dog with its throat slit open and its blood dripping into the bathtub.
Something on the bathroom mirror catches her eye she turns around. Written on the bathroom mirror in her dog's blood are the words "HUMANS CAN LICK TOO".
Those are just to start off. Not really scary... I'll look for good ones.
