Come true , came true , come true ??

They're all okay by me. The first one is a compound noun: "She is my dream-come-true!" (I'm not sure about the hyphens.)

If you want #'s 2,3,&4 to be sentences, you must capitalize the "M" and place a period at the end.

- A.

Thanks Avangi

What about The dream come true

Our dream come true ?

or

The dream has come true

Our dream has come true ?

and if someone is "slang" what is it ?

No, "My dream come true" is not correct grammar as a stand-alone sentence. Dream is 3rd person singular, and requries "comes."

Pisces What about The dream come true As GG has said, it's not a sentence.

Our dream come true ? (as a question) Has our dream come true?

or

The dream has come true (okay - Needs a period.)

Our dream has come true ? (as a question) Has our dream come true?

and if someone is "slang" what is it ? Low register

Our dream has come true

PiscesFinally , my dream has come true

is it right ??

Two things:

No space before the comma, and end it with a period or exclamation mark.
Finally, my dream has come true!
Finrally, my dream has come true.

Pisces Hiwhat is the right form my dream come true my dream came true my dream has come true my dream comes true ???

My dream came true

my dream comes true

As complete sentences, all are correct except for my dream come true.

But you need to start with a capital and end with a period.

Your dream came true
