Here's my story, happened in September 06.
My school organised a study trip to Pulau Bintan, Indonesia. An architecture study trip, we spent the day doing a mini case study of our own hotel building.
The hotel resort is built at the edge of a mangrove swamp, and from the main public road, it's a 5 minutes drive to reach the hotel, both sides are forests. There's a big golf course surrounding the hotel. So yea, we were in the middle of nowhere. The main road is already very rural.
After our study of the hotel, it's free time til the next day. At around 10:30pm local time we decided to go to the beach to catch the stars. As we live in the city, a sky full of stars was quite a sight. So we sat on the beach admiring the stars. Then, someone suggested we move to a darker part of the beach (there was a floodlight at our area).
We walked estimated 100m down the beach, when suddenly I say a bluish white orb of light drift slowly in a "S" shape across the beach. At that moment, one of my friends suggested we turn around, "in fear of muggers and robbers" he said. We walked back along the beach, and suddenly I have this very strong feeling that someone was watching us intensely, following us and I instinctivly turned around, and there's no one there. Another friend commented "do you guys have a strong feeling we're being followed?". Somehow I, in my mind visualised it as a man, standing somewhere near where the 'orb' was, looking at us from the distance. After a while the feeling dissipated.
When we returned back to the hotel, the whole group of us went into a room and discussed what happened. Not everyone said they saw the flying light. Almost everyone felt being watched and followed, and I felt it before my friend commented about it. And the instance I turned around, a few others looked back too.
I'm still wondering what happened that night. Ball lighning? Or something more supernatural?
