There was a story about a person who received text messages with just one word repeated over and over: 'Die'. The person didn't know who it was from and started to feel really paranoid. They changed their number, but the messages still found a way to reach them. It turned out to be a glitch in a new messaging app that was sending out random, menacing messages to some users, but it was really scary until they found out the cause.
In one story, a character gets texts that are just a series of numbers. At first, they think it's a wrong number. But then the numbers start to form a pattern that seems to be coordinates. When they look up the coordinates, it leads to an abandoned place in their town. The texts then start to say 'Come here if you dare'. It's a spooky situation as they are being lured to an unknown and potentially dangerous place.
Sure. There's a story where a girl named Gabby starts getting text messages from a blocked number. The messages say things like 'I'm in your house'. Gabby is initially scared but tries to rationalize it. However, as she walks around her house, she hears strange noises that match the timing of the text messages. In the end, she discovers that it was her prank - loving brother all along, but the initial fear was very real.
