First of all I have to say that I really enjoy this thread, thanks for posting!
One of the most strange events in my life took place about six years ago, when I was at a students' summer camp with my boyfriend. We were staying at
a very small town by a river. One evening we were walking back to the place we were staying at, it was getting late and the streets were completely
empty, but anyway my boyfriend decided to stop on the bridge to take some pics of the town lights reflected in the river. He started experimenting
with different settings in his camera and I was just standing there waiting. Suddenly, I became aware of someone else's presence. There was a woman
standing right next to me (I didn't notice her approaching). I took a look at her - both her clothes and skin were yellowish, what made her look
quite strange. She was wearing an elegant suit and her hair were neatly coiffed, but the yellowish colour and sunken cheeks and eyes made her look
rather sick and sad. She didn't have any handbag or anything. My first thought was that there was a party taking place nearby and she just went out
for a gulp of fresh air, but the entire town was silent and the lights were off.
My boyfriend didn't notice her at first. She approached me and asked who we were, in a low and hoarse voice. I told her that we were students and I
poked my boyfriend because I really wanted to go, but he was so absorbed with taking pics that he didn't react, just as if he was in a trance of some
sort.
'You'd better have as much fun as you can... As long as you can', the woman answered. It sounded rather like a piece of advice, not as if she was
threatening us or anything, but anyway I started feeling uneasy. I told her we had to go and just grabbed my boyfriend's arm and we started walking
towards the other side of the river. I took a look over my shoulder several times and noticed her following us. By that time we were both feeling
rather uneasy so we started walking faster. There was no logical reason to be afraid, but there was something about that woman that gave me
goosebumps. When we reached the other side of the river, we looked back oncce more and she was nowhere to be found. She had no time to walk back to
the other side and there was no place she could hide herself at. She literally vanished into thin air in the middle of a bridge.
We really wanted to go home and almost run to the place we were staying at, just to find out the at the gate has already been closed

We had to
call the caretaker and make him open the gate, of course it took him ages.
