Dream "derailed"?

Assuming that "dream" refers to one's fondest hopes or plans (and not the kind you have while you're asleep), I think "derailed" nicely captures plans that go off track, i.e., awry. "The flip of a coin" is a common metaphor for random chance. What do you find strange?

I just find it odd that the speaker used "derailed" instead of "squashed"/"destroyed"

Suppose we had these conversations:

Me: I had a strange dream last night. I dreamed I was starring in the film The Great Train Robbery.
You: What happened?
Me: I don't know. The dream was derailed.

Me: Ever since I was a little boy, my dream was to be a train engineer.
You: What happened?
Me: It never happened. My dream was derailed.

You: Pleas

Thanks for devising that lengthy example!
Also, I think that the expression such as "at the flip of a coin" and "at the drop of a hat" is used to indicate HYPOTHESIZED
situations, but here in my own example the incident has obviously already occurred, hence the confusion.
Again, just MY though, though.

Thanks again!:)
