I once heard from a friend that his uncle had commited suicide.. shortly after..they heard someone cryin' in a corner of the kitchen.. when ppl went to check they didnt see anyone there.. later on i think they went to those "mun mai por" (u know those chinese ladies that contact ghosts) and she said that it was my friend's uncle in the corner cryin' at nite
i dun remember how to put him to rest..but eventually they did.
