Thread: Please help: Something that I've dreamt about through my entire life

As long as I can remember, I've had this very same dream theme (at least once a year) that I don't like at all. It would be greatly appreciated if someone gave me their thoughts about this because I've asked about this before both here and on other forums and never really got an interpretation. I know there's a lot of ppl who want their everyday dreams interpreted but this is nothing "everyday" so please give me your thoughts and a few minutes of your life and I'll be very thankful.

The theme is very simple, it contains only 2 elements (with various random surroundings) that goes from being one, to many, and the dreams come with varying degrees of fear/despair.
In these dreams, there is railroad tracks in front of me stretching from the right to the left (or other way around) and I have to cross these tracks since there is no way I can go around them. I look to both sides, but see no trains coming. But once I get up on the actual track there is a train comming at extreme speeds, almost running over me (they aim for my death). Sometimes it's just one track, sometimes there are many I have to cross, and sometimes my movement speed decreases severely once I get up on the track(s). I always evade them though, I never die. But I always feel like Im "not gonna make it".

I have no idea what these dreams mean, since it has nothing to do with the "normal" interpretations of trains or railroad track. I think it's a dream related to fear of something, but of what I don't know.
The last time I had a dream like this (which was two days ago), the theme had changed slightly. There was a railroad crossing now (road crossing a railroad) and the safety bars where down. I looked at both sides but saw no train, so I thought about crossing it anyway but for some reason I didn't. So I waited. And after a few seconds I heard a terrible scream from someone else getting run over by the train somewhere.
