another dream just now!

i dreamed that there was this woman staying with us in a weird version of our house (like i had a brother). she was very charming, and my "brother" really liked her. one day, though, i decided to look her up on the internet and i realized that she looked exactly the same as this wanted serial killer who had killed dozens of people by using her charm to get close to them. i showed my parents, and they sort of believed me but found her too charming to actually join me in doing something about it. so i came up with this really stupid plot to get her arrested. i just called the police and told them to take her. for some odd reason, it worked and she was arrested. the police, though, were this really strange kind of police and they didn't have any guns or anything legit. she flirted a lot with the policeman who was supposed to be looking after her. he, consequently, didn't pay much attention to what she was doing and it looked really easy for her to escape. i became terrified for my life, naturally. then for some reason, we got on a train. as we got on, the woman mouthed across the train at me "you better look out" while making a gun with her hand at me. then i woke up.
