Dreamed of a killer

Okay so I put some mugswort under my pillow because it’s supposed to give a person profetic dreams. Nothing happend. The next night I put it in a red bag and I had a dream late in the morning. In the dream it was about 10:00p.m. And I was standing in my kitchen with my cell phone, my parents were in the living room watching tv together. I sudenly started to get texts and calls from an unknown person. In the texts the person said thing’s along the lines of “I’m watching you” and in the calls I’d get the same response or just some heavy breathing. Then I started getting pictures sent to the phone first of myself in the kitchen taken from outside but then they were of a girl who was dead. She was upside down and all scraggly like she had been thrown around and the girl looked pretty simular to me which I took as what would happen to me? So when I got the picture I flipped, I started screaming and running to my parents to show them, and then suddenly I wasn’t like that just didn’t happen and I was just standing in the kitchen panicking. Then I got a phone call again. It was a man saying he just wanted me to go out with him once, just once. I agreed hoping that if I did he would leave me alone afterwards like he promised. That was it. I told my mother about the dream in the morning and she was like “psh what did you watch last night” and honestly I didn’t watch anything along those lines I watched pride and predjudice for the hundreth time. Now I did read a book five days prior about a girl who is beeing stalked and her wican friend dreams about it and save’s her but it was days before the dream and I wasn’t thinking about the book prior to falling to sleep, and nothing in the book really matched up along the lines of what happend in my dream. I told my sister about the dream and she seemed somewhat concerned, and asked if I even got pic. Txts on my phone which I don’t beleive I do. So now I’m going through this debate in my head of whether or not this dream actually meant something. I have had dreams about thing’s to come before but they’re in the very distant to somewhat distant future. One about the end of the world and 1 about me meating a teacher this year and we’re supposed to help each other through life. I don’t know what to think or do and I’m really looking for a second oppinion on all of this.
