> 誰かの胸の夜の空に伝えたい気持ちが生まれたら

Which meaning is suitable?

  1. When you have a feeling that you want to tell someone’s night sky in his heart. 
  2. When you have a feeling that you want to tell something to someone’s night sky in his heart. 
  3. When someone has a feeling that he wants to tell (in his night sky in his heart). 
  4. When someone has a feeling that he wants to tell something (in his night sky in his heart). 




I would read it as AにBが産まれたら ("when B is born/produced in/at A") where A is
誰かの胸の夜の空 ("night sky within someone's heart") and B is 伝えたい気持ち
("passion/feeling to tell something (to someone)"). に is a static location
marker (i.e., where something exists) rather than a destination marker here.
So 4 is the closest among the four options.

This interpretation aligns with what's written in the next line:

> 伝えたい誰かの空へ向かう  
>  It (=伝えたい気持ち) will head to the sky of someone he wants to tell (the
> message) to

So 誰かの胸の夜の空 in the first line is clearly a starting point rather than a
destination. This is why option 2 is wrong even though it may seem
grammatically possible. Imagine something like telepathy is happening, and 流れ星
is the invisible message itself (or its "carrier").
