why do i never come across ghosts in a pub or a concert...why does it have to be in a secluded upper floor of a spooky mansion ..and if someone played white zombie right then..then whoa! lol

im not the novel reading types..but anything to do with ghosts and hauntings fascinates me. i read into it a lot. so, do i believe they exist... one side of me says no, they dont. it;s just our mind playing tricks on us based on the surroundings. i would presume it's our subconcious which reacts in a certain way to get us more alert and in the process, any activity such as door opening or sound of music gets really highlighted, to the extent, even a reflection can throw a fit..
the other side of me says, yes, they do exist. why do i say so...? well, the fear of the unknown really. i have never come across any visions or sound per se.... but one of my first cousins mansion was kinda spooky. i mean it was a beautiful vintage house with 8 bedrooms in the groud floor and 5 on top.. it was vast estate overlooking the creek and surrounded by dense forest, if one looks further, you could almost see the sea.. now the thing is, none of us was allowed to go to the first floor...and this was when we were 15 or so.. one evening, i decided to go and check it out.. i was this half chicken - half dare devil sorts.. time: evening, i slowly made my way through the wooden stairs, it took some time to reach on top as it was steep and it had far more number of steps than i expected, i finally reached on top and the palce was mute dark, with a long verandah overlooking the creek, there was no moolight, pitch dark with just a tad bit of reflection .. i moved closer to one bedroom, door was too huge for me ot manage, but some how i pushed in, took a few, small steps inside..looking at the shadow of huge furnitures and the bed in center kinded shook me up... i sorta felt a very strong echo of energy then, could be my adrenaline, cud be the rush, dunno, but i was certain i wast alone there and that if i stayed for a minute longer, that force would swallow me in. the errieness and the smell was just too gothic ! but, when i think of it now, i still challenge myself with a question. and the question is, would i sleep overnight in that room today... and the answer is..
bottomline, i think it;s more to do with each one of us' capacity in terms of handling emptiness and the fear of the unknown lurking in dark... for eg. even if you are a assured that the room is empty, the moment it goes pitch dark, sooner or later, we will panic.
