Analysis of "It is like a dream come true"?

Question

I've been unable to grammatically analyse the sentence> It is like a dream **come** true.To me, it should either be> It is like a dream **that has come** trueor> It is like a dream **comes** true.Or peculiarly, *to come true* could be used as a phrase here, and *come true* should be seen as a modifier.Which interpretation is correct?

Answer 1

This is a simile. It has the same structure as: The dried batter was like concrete.

It is like a dream come true. Simile.

explanation of phrase "dream come true", from the Internet: “My brother-in-law got a job in another state, paid back all our loans to him, and moved out. It’s a dream COME true.”

That’s a shortening of “It’s a dream THAT HAS COME true.”
