I don't exist!

So there's this 17-year-old girl her name is Abigail Reese and she stops existing September 3, 2019. And by that I mean she was a very stressed out teenager and she would always go on midnight drives. No where specific she would just drive for about an hour or two. One night she goes on her normal drive and she leaves out the window like she always does. She leaves and then comes back to her window being locked which is weird because she didn't lock it when she left. So risking getting caught she goes through the front door of her house and goes to her room to find a stranger in her bed! In shock she runs to her parents room and bangs on the door. Her dad then answers and she starts telling him what is going on. He looks so confused and starts yelling at her. Telling her he doesn't know her and she needs to leave before he calls the cops. Her being so confused she grabs her stuff and leaves going to the police station. She arrives at the police station and start telling them what's going on. She says "help there's a intruder in my house and I think they did something to my parents because now my parents don't know me!" Police man "Calm down and tell me your name!" "My name is Abigail Reese!" Police man " if this is a prank you can run along!" Her being so confused she ran out and to her car. Crying leaning on her car she looks up her social media and it's all gone! She then sees a stranger leaning on her car he says " So no one remembers you either?I heard you inside that's why I was there now I know I'm not crazy. I woke up this morning and no one knew me either as if I don't exist!" Her bing speechless he continues "Now are you gonna stand there being confused or help me figure out why the hell we don't exist no more!?!"
