Then why did you discount it half an hour ago?
Anyway, ghost tours are never freaky, although the reason why these ghosts exist are usually quite interesting. Some people are hung, others were pushed out the 2nd story window by their father. The stories are cool.
My grandfather, 2 uncles, and grandfather's maid have all seen ghosts in my his apartment in Hong Kong. All on separate incidences, but one time I think my uncle and the maid saw them together. Not sure of the exact details, but freaky indeed.
