[Japanaese>English} Writing a comic - I need validation of a Japanese sentence translation

Hi, this will be posted to a 5 million likes page and I need to know what's written here because I wouldn't want to offend anyone reading it. The character is like a "mysterious woman" that says something "mysteriously" like in a fortune cookie sort of truth-telling. thanks!

Sentence is:

振り向くな、振り向くな、後ろには夢がない
