What does this mean?

My question sounds so corny, and stupid, but its just something that has been bothering me lately.

I had this dream that my boyfriend told me he didn’t love me anymore, and that he loved this girl named Brooke (She’s in his AP Algebra 2 class) so I start thinking that this is going to happen, and I hate the thought, because I love him so much.

Another dream I’ve been having a lot more lately, is that I’m sitting at a park, and someone kidnaps me and just basically, kills me. I just think that its a fear that I still worry about which is why I dream about it. Someone did try to kidnap me, which is why I have that fear.

Why do you think I’m having these dreams? I know it sounds dumb, but I want to hear your ideas.
