I had a dream last night

I'm a wizard

I've kind of noticed that my dreams slightly reflect what series or movie I watch. Last night's dream is based on Harry Potter. It starts with me having something from the HP universe that has been transitioned into the real world. I'm not sure if I took it (I think it was a book) or if I was just another carrier. Anyway, the dream begins with me being chased by a group of girls that were of varying ages (10-16ish) and they really wanted the book. The chase took place in a city I've never seen before. My brain probably puzzled together images of various places I' ve seen before OR set it out in New York because I'm currently watching How I Met Your Mother and Suits which are both based in that city. As I'm being chased by the group, I was also running from Voldemort. He needed what I had and, well, he wasn't going to get it, I had to make sure of it, I needed to protect that book. Why, you may wonder? I have no clue. So at this point, I'm being chased by a group of girls (probably from the HP universe but they were all wearing normal clothes) as well as a deadly character, probably set out to kill me in the process. Voldemort had also tried to disguise himself by working at a food stand in a park to trick the Hogwarts students but I could somehow sense his presence from a distance.
I woke up from the dream to go to the toilet and when I went back to sleep another dream started which I don't remember much of. The main point of it was that I was having lunch with a couple and another person on a bench which was floating right above a river.
