Alright, I thought of another one:
In 2002, my then-partner and I went to see a Tori Amos concert. We were in our seats waiting for the show to start when this rather beautiful biological man with long dark hair, dark eyes, and a trench coat came down the aisle, walking in a way that it seemed he was floating. He stopped near us and stared intently at the stage. I must have gotten caught up in his aura or something because I looked at him and heard myself say, "You're looking for the red-headed girl."
He turned toward me and kind of smiled and said he was. He looked around a bit and I believe we may have spoken for a minute or two. He had a very unusual, 'otherwordly' quality about him. My then-partner said something and I turned to her. When I looked back, the man had vanished. I mean just disappeared and I couldn't have looked away for more than a second.
We talked about him for a minute or two and tried to locate him but couldn't. The show started and we forgot all about him.
Here's where it gets weird:
We both went to bed that night and had the exact same dream about him. (No, not like that. lol!) We were at a type of tea party a-la "Alice in Wonderland" and he was there. It was more involved than that but when we woke up, we realized we'd both dreamed the exact same thing.
When I do tell this story, I say it's the one time I may have met a vampire (though I don't actually believe in them). He looked like he'd just walked off the set of "Interview - With the Vampire". This was before it was cool for vampires to sparkle.
