Can someone help me understand why so many train tracks? so heres my dream its also in my journal.

"Ok so my dream start off with me sitting in my van and there’s this guy to my left that my a fit about something then a crowd gathers and he decapitates him self, I see it 3 times same person like a replay I remember the last time, I said I cant see this and right before he cut his head off I looked away and drove off from then I remember a bunch of my friends in the can talking a long road in front of us curves every now and then, as I turn I see train tracks just one so I pass it, no train, then I hear the horn of a train, more tracks 2, 3 then 6 and I remember the last one, just one by its self I do a sharp turn avoiding my death, and awakening. I the remember then getting out and like walking home as I encounter a bum/ thug and like he tried to kill me or rob me so I ran home, as I thought to my self I better run fast then I remember everything like flying by me, like tunnel vision then I was in my home. I got some pistols from who knows where, for those who play CS: S they were the Dual .40s. As I did this, the guy came through the front door I shot at him a couple a times then I ran outside and I thought. “I need to get on the roof, or fly out of here.” So I ended up doing this super jump instead of flying I land safely on the roof then I laughed nervously as the guy came out shooting at me then, he stops for a moment wondering how I got on there, as he did this I shot at him a couple times as I ran to the opposite corner as I put my pistols away getting ready to fly, again. I said to my self “Ok I’m gonna try, no i'm gonna do it, I will.” I jumped up trying to attempt the anti-gravity lift like Neo From the Matrix, well. As I got a good 15 feet higher I came down, by then I got woken up."

That was my whole dream and my first LD...i think lol
