I'm 20 years old now and still get this dream basically it started like this
I was in school and was playing around with my friend  having a laugh when we heard screaming. We ran through the corridors that seemed to get longer to find them litterd with bodies of students. We got to the main door it was locked so we ran into the bathroom scared. She ran into one stall and I ran to the opposite side and slammed the door. It was quiet for a few minutes when all of a sudden I heard the creek of the bathroom door I heard my friend hyperventilating  as I heard clinking of claws across the floor. I heard the door get ripped off its hinges and my friend scream. It made my blood run cold. It was shortly cut off and all I heard was her gargling on her blood. I coverd my mouth in fear. Fearing for my life at this point I heard a sicking snap and a dragging sound that neared my stall  when the door flew open there was nothing there but a pool of blood and my friend laying dismembered. Body parts all across the floor the creature was nowhere to be seen. As I head towards the door shaking I hear a deep but low giggle behind me and turned to see a little girl dressed in red with long brown hair and black eyes blood all over her face grinning she whispers you forgot me. And I woke up
