One night I started hearing scratching on the front door I checked through the peep hole as always having been paranoid for about five years since the incident, when I checked through the peep hole..there was no one there and I began having flashbacks, Ill save the incident for later, I decided to put the latch on and open it that was the worst thing I could have done ... The dog like creature forced its snout through the door and began growling and thrashing around trying to get through I realized it was starting to break the chain that was holding the door shut... I ran to the kitchen and grabbed the most practical knife to deal with a dog and prepared to fend this thing off...it turned the corner moving like a demon fast but unnatural, as it barrelled at me I shoved the knife forward into the creatures chest it slumped over but seemed not to stop moving but only to pause it began to get up as I ran to get my phone and dial the police, as soon as picked up my phone I realized that I had no reception I looked around hoping for something that could help me I realized my grandpa had left his old military uniform and pistol in his old bedroom I began to Sprint towards his room but realized the creature was just behind me I tried to get the door open forgetting that it was locked in that moment the thing rammed into me, as I hit the ground it dug it's teeth into my leg I began hitting it trying to get it off then I saw that the knife was still in it's chest so I reached for it and tore it out of it's chest it let out a blood chilling scream, what I thought at that moment was that this was a demon so I got up found the keys to my grandpa's room as soon as I got the door open I shut so that I had a little time to find the pistol, I found the pistol in the bedside table and checked the ammunition, three rounds, I cocked it hoping to God it wouldn't jam and hoped for the best.
