Is it normal a dream affected me this way?

Basically, I had a dream a couple of weeks ago that has stuck with me. It is plausible but highly unlikely, but I've thought about what I would do if it became reality.

This is mainly about my crush whom I will call "Billie Joe" because his idol is Billie Joe Armstrong. He's a great guy. Anyway I had this dream that he had a crazy ass stalker, she was constantly texting him her selfies and wouldn't let him have any contact with anyone, especially me. This made me very angry.

In late August, I bought a sticker from him. We don't live close to each other so I shipped him the money. He told me his friend "Tom" has the stickers. Tom is my friend too, I got to know Billie Joe through him. Anyway Tom said he would give Billie Joe the sticker to ship to me. It's been a couple of weeks, it still has not arrived. Normally I wouldn't care about something so trifling like a sticker or losing one dollar, but I keep thinking about the dream I had. What if there IS a stalker? I've decided that if it's true and I find out who she is, I'm going to make sure I get my money back out of her pocket. I know it's only one dollar, but I just don't want her to have her way. I want her to get her karma. Oh and Billie and I have talked lately, he usually texts back but last time I texted him he didn't...curioser and curioser.

Before you say anything, I have NOT mentioned this to anyone and I do not plan on doing so until I see smoking gun evidence that a stalker exists. I know it's probably not true, I just can't get it out of my head. Normal or am I delusional?
