After searching several websites for girl's names, I could not find an English name that means "dream come true". The best choice might be the name 'Hope'. The noun hope means a feeling of desire for something good and confidence in the possibility of its achievement. In the last 100 years, the girl's name Hope was one of the top 500 girl's names. It is always considered to be a good future, positive and encouraging name. I hope you like my answer :)

In the United States, we do not pay much attention to the meanings of names. People may look them up out of curiosity but they don't take them seriously. When I introduce myself as "Dan" _nobody_ ever thinks "God is my judge," it doesn't even flash through the background of anybody's mind. "Hope" can be a name for a woman. It's not terribly common, it's a little bit old-fashioned, but it's not strange or unusual. If there is a Chinese word that means "hope my dream could come true" she could simply use that. She could change the spelling to make it look more English if she likes. In the United States, people can and do simply invent names, particularly for women. In the United States people will name their children after (give them the same name as) members of their extended family, or friends, or famous people they admire--or fictional characters that they like. That is to say, the "meaning" of the name "I hope my child will be like someone else who has that name." Also, parents often pay attention to the sound of the names and how they go together.

In addition to the name "Hope", I'd suggest "Joy", "Felicity", or maybe "Destiny". They have the feeling of something good happening, such as a dream coming true.

I agree with Paul. Asking an English speaker for a name with a specific meaning won't get you anywhere because English names don't *have* meanings. Don't believe websites that list names and their meanings: those are not meanings, they're etymologies, and ones which native speakers are completely unaware of. To give you an idea of how unimportant meanings are to English speakers, I have know idea what ANY of the 'meanings' of the names of my parents, sisters or friends. I had no idea that my own name came from Ancient Hebrew until a priest told me very recently, and apparently it meant something like "Servant of God" (I don't remember exactly) in Ancient Hebrew 4000 years ago. When I told my parents, they laughed and said that it was the first time they ever heard that, and they found it funny because they and I are all atheists. A small selection of names are the same as an English word (in particular, quite a few girls' names are the same as words for flowers), but these are a small minority. And no one would think that the name, for example, 'Rose' *means* the flower, they'd just think "Rose's name is also the word for a flower". If you want an English name and you don't care about it sounding like your Chinese one, the ONLY thing you should care about is how it sounds.

Richard gave the best answer. We don't really have names that mean a sentence. They usually only have single word meanings. Like 'strong', 'brave' and 'beautiful' or things like 'God's grace'. So names with the meaning of 'hope' is the best option.
