Can someone interpret this dream for me?

Okay, so I like this guy, let's call him A. So I'm in 7th grade, and he's in the 12th. [I knoww, way older than me, but whatevs] So this was his last year.

In my dream I saw that I was like in a bus, and he was there and a bunch of other people [well, teens. not adults]. And then like were really bored, so I got up, and went something like Okay lets all introduce ourselves, or something. Then I randomly get some vision of a car blowing up. Then A gets called off the bus..and then Idk how but I can see what and where he's going, even though I like wasnt there. Then, he was taken to a hospital, and there his mother was in a hospital bed..and he was standing in the doorway motionless, watching her. Then his youngest sister came and was like holding a teddy bear, and sucking her thumb [she's like 3]. She was also just standing thr. Then his other sister came in, whos in 2nd grade, and was like just standing also. They were like in shock or something. Oh btw, The 2nd grade sister had gotten out of a hospital bed then came. As well as the youngest.

Someone please care to explain? I had this dream quite some time ago...like weeks ago, but I just wanna know what its about. And, I'm most prob never going to see A again cause he's done with school now, and he's going to uni now. So yeah.

Well, anyway, thanks for your help. :D
