Whether it means anything romantic or not, who knows. There can be other energies around a friendship besides romance.
But here's another little anecdote: my dad was overseas in WWII, and of course my mom usually did not know exactly where he was. I mean, she had a general idea, but soldier's letters home could not discuss troop plans or anything of that nature.
Well, one day, when she hadn't had a letter from him in a while, she suddenly felt SO strongly that he was close, and that she would see him soon. She said she felt really happy all afternoon, because she just KNEW he was on his way home.
Late that afternoon, the phone rang. Dad: "Hi honey, guess where I am? In San Francisco, and I'm on the flight to see you tomorrow!" She said: "I KNEW you were back in the U.S.!"
He got all upset and said "You KNEW? How did you know? No one was supposed to know!"
She had to explain that no, no one told her about it, no, she had not seen any mention in the newspapers of his division or anything like that, just that she knew, at a very visceral level, that he was someplace close.
