There could be a young couple as the main characters. They are excited to start their new life in a new home but end up facing the horror elements in the game.
The plot might center around a group of friends who decide to explore an abandoned house in the 'Home Sweet Home' horror game. As they enter, they find that the house has a life of its own. Doors close on their own, there are creepy noises everywhere, and they soon realize they are not alone. There could be a backstory about the previous owners who met a grisly end, and now their spirits are out for revenge on anyone who enters the house.
One scenario could be that a family moves into a new home. At night, they hear strange scratching noises coming from the walls. Every time they try to find the source, there's nothing there. As time passes, the noises get louder and more frequent, and they start to feel like they're being watched in their own home.
I once sent my DNA for a home test. When I got the results, it said I had a high risk of a genetic disease that was very serious. I was so scared at first. But then I realized these home tests might not be 100% accurate. I went to a professional doctor and got a more comprehensive test, which turned out to be negative. It was a real horror moment though.
There was a family living in an old house. One night, while they were all in their beds, the front door slowly creaked open. A masked man entered, making no sound as he walked through the rooms. He got to the bedroom of the youngest child first. The child woke up and screamed, but the man just stared. Then he started to move towards the other rooms. The family huddled together in fear until the maniac finally left as mysteriously as he came.
Once, a friend of mine decided to do home waxing on her legs. She bought some cheap waxing strips. As she pulled one strip off, it didn't remove all the hair but instead left a big patch of sticky wax on her leg. She tried to wash it off with soap and water, but it just made it worse, and her leg was a gooey mess.
Adding a sense of isolation can make it more terrifying. For example, if the home is located far away from other houses or in a desolate area. The characters can't easily get help or escape if something goes wrong.
One possible horror on the last train home could be encountering a strange and menacing figure. Maybe it's a shadowy person who just stares at you without blinking, making the hairs on the back of your neck stand up. You feel trapped in that small space with them, and there's no way to escape until the next stop.
Once, a girl was home alone at night. She heard strange scratching noises coming from the attic. As she slowly walked up the stairs to check, the lights started to flicker. When she opened the attic door, a cold wind blew past her. She saw a shadowy figure in the corner but when she blinked, it was gone. She ran back downstairs and locked herself in her bedroom, too terrified to move until her parents came home.
