Traducerea - Portugheză braziliană-Japoneză - então, você apareceu em minha vida trazendo-me...

Romanized:
Sore de anata wa yume no yô ni, watashi no jinsei ni arawarete kuremashita
Literally:
After that, you appeared in my life like a dream (come true)
---Note---
The image of "magic" in Japanese isn't very good: the word for magic is
mahô / 魔法
and it literally means "the devil's way"...
"As if in a dream" is a better, more natural translation into Japanese here.
