What does my dream last night meant?

It was an ex-girlfriend of mine, actually one of those True Loves, and we were hanging out at a pier, just her and I. It was like a Disneyland but on a boardwalk. Felt like a date. Felt good.

I have not seen her in three years, much less talked to her, but every day she appears in some thought or feeling of mine.

What could it mean?
