Parsing and meaning of a song verse

Question

I'm trying to understand the opening of an anime song, but I'm stumped on a couple of parts by (I think) a similar doubt; this is the lyrics.

Here's what I don't understand:

夢を持ってきた

言葉じゃ足りないユメのアリカ

While sung, the parsing seems like 夢を持ってきた言葉じゃ / 足りないユメのアリカ, with a pause after じゃ; I understand that could just be for musical reasons, but when I first heard this song I thought 夢を持ってきた modified 言葉, and 足りない referred to 夢, giving something like “The words that brought dreams are the place [where] dreams aren’t enough”, which doesn’t really seem to make sense; the translation I found is:

You brought a dream here,

The place of dreams that can't be expressed with words alone

which makes sense, but I can't really understand how that translation comes from the original lyrics.

I have similar doubts on 色が乗ってきた / 心を広げるイロのキセキ, which sounds to me like "The miracle of the color expanded by the heart on which the color is", but my doubts here could just be like those on the previous verse. Edit: I wrote about this too not as a separate question, but because I think it's another example of the same doubt.

It's quite a while I'm trying to understand this; if the translation parsing is right, and 夢を持ってきた is to be translated per se as "You brought a dream", without the lyrics I didn't understand the parsing; I also asked to a friend of mine who is fluent in Japanese, but no luck.

Answer 1

Generally, Japanese song lyrics tend to be loose in grammatical integrity, and much more for those whose lyricist is Hata Aki (I mean!).

While sung, the parsing seems like 夢を持ってきた言葉じゃ / 足りないユメのアリカ, with a pause after じゃ; I understand that could just be for musical reasons

Regarding this, all lyrics I find make a line break between 持ってきた and 言葉, so I think we can postulate that the gap does exist there in spite of how they sing.

Now, grammatically unambiguous facts are that:

• 夢を持ってきた: "[somebody] has brought a dream"
  Note that the subject is unmentioned. It is quite likely 君 from the context, but still.
• 言葉じゃ足りないユメのアリカ: "the location of dream(s) which words are not enough for"
  There are ambiguity on whether 言葉じゃ足りない qualifies ユメ or アリカ. Also, a relative clause as sentence is a common rhetorical device to emphasize the predicate, compared to "in God we trust", "little did he know" and such.

Then anything beyond those things are all matter of interpretation or imagination. Of course, one can reasonably guess that who brought a dream is "you", but it is not objectively guaranteed. (For the subject of 色が乗ってきた "acquire color(s) / got colored up", I really have no idea; it could be "you", "I", or "we".)

I thought 夢を持ってきた modified 言葉, and 足りない referred to 夢

With above, whether 夢を持ってきた modifies 言葉 is grammatically unwarranted, but I'm strongly inclined to think that the two lines are separate. Besides the meaning, they both have 夢/ユメ, which is a point favoring the view that they are parallel descriptions sharing the common focus on "dream" (Japanese use less anaphoric pronouns, and often repeat the noun itself). I do believe 言葉じゃ足りない modifies ユメ to mean something like "dream beyond words" (rather than アリカ, which would mean "the place untellable by words"), but it is not a most natural collocation in Japanese either.
