SWAMP?! 
You know, on a trip to Malacca when I was in primary school, we
lived nearby a place where many big tombstones were located. Big as
in, really really big, the length of two cars.
It was very creepy, especially when sometimes we returned to the
hotel late at night. It was rather secluded.
Then one night, there was this rumor that a teacher saw a ghost,
and it just scared everyone that we gathered in one room and people
just started crying.
Earlier on, there had been incidents reported, of people hearing
the taps in their rooms going on by itself as they leave the room.
Also, a neighboring roommate said she saw sparks coming out from a
drawer as she opened it.
As my friend and I were leaving the room to take an elevator down
to our rooms, I thought I saw the bin move by itself.
