Big mood
I've yet to call somebody close to me a character name, but this almost happened with a stranger.
I walked into a small café and immediately noticed that the only person behind the counter looked very much like how I imagined the main character of my sci-fi novel. On top of that, my character also works in a bakery-café—and the name on this woman's nametag even started with the same letter. (My character's name is Laeneth, and this person's name was something perfectly normal, like Lauren.) I had to watch myself to make sure I didn't call her the wrong thing.
I'd never seen her before in my life, so there's no way I could have based the character off her by accident or something. It was surreal. I almost wanted to take a picture of her, but didn't because that would be rude.
Edit: I live near that café, so I've been back there, but never saw her again. This totally means she was a ghost or something
