I hav had the freakiest dream I ever had. Why did I dream this?

Okay I have a boyfriend that goes to a differant school, and one guy used to like me that was in my school and my church. They have the same name but I'm going to call them B1 and B2:
O my...  **starts shivering** my dream scared the cuss out of me!
  Okay. So I was in class right? And I ask to go to the restroom. Teacher says yes so I hall walk there. I open the restroom door to find no stalls, no sink, just grass looking carpet, blue walls, and beside me, a giant set of gold stairs like off a Broadway musical. Who's that sitting at the top? B2. he says hello and I am surprised because I know he can pull strings but this is crazy. I say hi back. He offers me a choice. He said his grandparents can pick him up 30 min before school ends. Then he says they can pick me up too. I was thinking , hey awesome! Go get a milkshake or something... Then he said "that's 30 min with your favorite pare of guys right here" and shakes his body in a weird way. Or I could have 2 little trinkets. I thought that I could just run away if he is thinking about sex (which he was..) so I said the first choice. He said that he said he was surprised I picked that choice. I was hounest and told him my plan. Well he got mad. So I can't remember what happened next but I do remember he tried to rape me an so I ran for the door but it locked behind me. He chased me around for awhile and I finally said "okay I will, but first I need something from my locker." of corse my plan was to run away once he let me out but I woke up before I got an answer.
When I woke, my reproductive system was throbbing. I went to the bathroom and I was cold, scared, and my teeth were chattering. I am still a little jumpy and it's hard to type when your shaking. I hope nothing like that happens ever again. I'm scared to be in my own bed... **shivers again**

Can someone help me? That thing emotionally scared me. I at least want to know what it ment... Please? I'll fan you.
