The Last Person to Receive the Text Message

At 11:47 in the morning, I received a text message. [Don't take the last bus after twelve o'clock tonight. I thought it was just a prank. But half an hour later, I really got on a No. 444 Bus that didn't exist at all. I survived that day. Early the next morning, the phone rang again. Don't look back. Since then, I have received a death notice every few days. Every text message means a new supernatural event. I don't know who the text message was. Don't even know... Why do all the dead people know me?
