What does it mean to dream of a girl that u liked before?

It merely means that you still like her and your subconscious mind in that particular dream made up a nice scenario.

I happened to notice that a woman whom I, to be honest, was in love with 15 years ago now has a Facebook page. I had happened to think of her for some reason the other morning, and typed in her name in the search bar ... and there she was. It's a newly created page. She wasn't on there before (and no, I'm not stalking her. Certain things remind me of her, that's all.) I'm not going to send her a friend request even. Our friendship was 15 years ago. Yet the subconscious mind remembers it like it was yesterday.
