A Night in HELL

I was walking towards the old school building, my 'friends' had dared me to take a look inside. The place had apparently been deserted since the 50's because of some fire. The place was now nothing but a two-storied pile of cinder blocks. I was at the entrance, the door was locked, of course, but that didn't stop me. Me being a curious soul, would have gone to the old school building with out being dared, but that just made me want to go even more. I pulled my lock-picking kit out of my satchel and had the door open in less than ten seconds. The door's hinges were very rusty and made an obnoxious creaking noise as I opened the door. 'Someone needs some WD40,' I thought to myself. The hallway was full of ash and burnt child remains that crunched when I walked. I headed into the first classroom I saw and switched my flashlight on, only for the batteries to run out.
        "Great," I said to myself as I smacked the flashlight against the wall, "now I have no light." I continued through the classroom when I heard the front door slam shut. 'Oh crap', I thought, me being paranoid and all, 'ghosts?'. I stumbled over a small desk and landed flat on my face, to add to my troubles, I was laying on top of charred skeleton. You wouldn't expect it, bu there was also blood all over the walls. I ran out of the classroom to find the door locked again, and really rusted. I tried to pick the lock and nothing happened. The door was metal so I couldn't kick it off its hinges, but I could still explore the building. By now I was close to scared out o my wits, thankful that I brought my knife and stole my dads .45. I went into the lunchroom, which smelled of gunpowder mixed with charred BLT's, as well as charred human. There is nothing worse than the smell of bleach and burnt human flesh. I walked around the room, making hardly any noise, when all of a sudden I felt a hand on my shoulder. I whipped around, gun in hand, and saw no one. Nothing was out of place, and the door was still open. "SLAM!" I heard the door close again, except this time it was the lunchroom door. I saw a chalkboard with 'Welcome to HELL!' written on it. I looked around for any windows or more doors, but I saw none. I heard someone walking towards my back and I whirled around with a roundhouse kick and narrowly missed their chest, but ended up hitting their shoulder. I heard them fall to the ground from the hit and ran over to them, gun ready, when they moved I shot. I kept shooting until I could see the blood pool under them. I sighed in relief and approached the body. I then heard a voice behind me "Wrong one," then a black bag was pulled over my face and legs and arms duct taped. Before I could make a noise I was hit over the head with something very heavy, and fell unconscious.

When I woke I could smell sulfur and sweat. The bag was still over my head, but my hands and feet were no longer duct taped. I quickly removed the bag and wished I hadn't. I saw a mess of gore scattered all over the room. From bodies with their stomachs ripped open to limbs lying detached. I felt like I would hurl, and then I saw my captor, a man clad in all black wearing a fedora to shade his face. He noticed I was awake and said
"Let's have some fun, shall we?" I didn't have time to reply before his finely crafted knife was slicing all over me. First he went for my arms and legs, then my face, and last but not least, he sliced my abdomen, releasing my intestines all over the floor.
