Extremely scary ghost stories?

It is one about somebody walking around town when they hear sounds in the alley. So they walk into the alley and they see a rolled up carpet and it looks really decent. No one else is around, so they decide to just take it home with them. As they drag it along, they keep hearing footsteps behind them and moaning sounds so they walk faster but whenever they turn around, no one is there. It is heavier than they think but they just ignore it and get home. They triple lock their doors and windows just in case. Then he puts the carpet in the living room, and decides to unroll it the next day. After a good night's sleep, they went into their living room and found it was trashed. They decided to call the cops but saw that the carpet was missing. They were robbed! So they walked to the kitchen where the phone was and saw the carpet. After dialing the police's number, they found that their phone was dead. So they headed for the door to go to the station and decided to quickly just set the carpet somewhere. As they walked into their library (this story was old-fashioned) they set it down and it unrolled by itself. It revealed a dead body inside, rotting with only little tufts of white hair. The man stood in shock, staring at the corpse, then it sat up where it was and screamed in a loud, violent, deep voice. The man screamed and ran out in fear. He ran to the police station in a state of complete panic and soon enough the cops were coming to his house. When they got back, the windows were shattered, the door wide open, and when they went inside, there was no evidence of the corpse to be found, just the carpet. The police told him to wait there but instead they called up the asylum and soon enough the man was in a straight jacket being taken there. As the van he was in rolled down the street, he glanced out the barred window one more time. He saw a rotting body carrying the corpse down the street, into the horizon. He screamed one last time before going completely insane. From then on, he was frequently visited by the memory of the corpse screaming up at him.
