Well problem for this kind of phenomena is its selectivity. It
doesnt happen all the time, or it happens ,but selective people can
see it.
The most haunted country in the world is supposedly Britain, and
the most haunted or mysterious place is the Glamis Castle,
belonging to Queen Elizabeth thru her mother. No one knows what
creatures or happenings lurks inside the castle.
However, these are special events, or secial places. Some homes,
like the Hampton Court may have scenes happening again and again.
It happens selectively at certain time, at certain place. Haha,
doesnt meant now I am typing on this pc, later when I die, CHOI, if
the HDB flat I am in is still occupied, people of later generations
can see my apparition still typing away.......
God, they might even see me wanking away, watching porn on my pc,
how shameful......
