Yes, your definition is absolutely right! It sounds like a good "chat up" line...😁

Dreaming something/someone into life basically means that whatever happened, or whatever person you're saying that to, is like a dream became a reality. In the context there it means that the person loved someone even before meeting him so much that it was like he/she was straight out of a dream.

Hi Jordi! "To cause someone or something that is in a dream to become real" sounds like a good definition. That person dreamed so much about her/him that the dream became a reality. What the person really says is that he/she loves him/her beyond any possible measure as if that love had already existed before they met (whoever says it, is really trying to sound very romantic about expressing feelings). Let's see what others say and figure out if I was right 🙂

Hi Jordi. In this context it means the person is like a dream come true.
