Even people who die in accidents or homicides tend to be there for more than several hundered years .I used to hear a girl & boy talk outside my house window for hours each day ( after shifting newly ) - after a few days finally we realised they were ghosts
Being Hindu I have some real interesting Ghost stories
In order to underestand what happens we must read the Real ghost stories :

I believe that they usually haunt the place they died - this is exactly what the stories usually tell
According a boy & girls who would sleep alone in their bed room - after tehy switched off their lights some where in the middle of the night , they could see a shadow a body dangling from the fan above
But nobody believed them
A girl called up her friend & mother shortly after she hanged herself
A guy who committed suicide would light up the candle each day in a mumbai flat for years after he had hanged himself inside that abondoned flat.
