The Forgotten Call

It was midnight when Sarah's phone rang. The number was unfamiliar, but curiosity got the best of her. "Hello?" she whispered. Static crackled, then a voice, faint and trembling, said, "Help me... I'm lost." She asked who it was, but the voice faded. Thinking it was a prank, she hung up. Minutes later, the call came again—this time, louder, desperate. "Please, help! I can see your house. I’m right outside." Panicked, Sarah looked out the window, seeing nothing but shadows. She locked her doors, heart pounding. Her phone rang again. This time, it was her own number on the screen. A voice identical to hers whispered, "You should have let me in."
