Simple question, you can discuss it further if you like.
Me, personally? Don't believe in anything of the lots. There are no ghosts, poltergeists, phantoms, whatever.
Same with "cases of extreme strength" or whatnot, there's a scientific and logical explanation for everything. I also don't believe in a god, but let's leave that out of here. [Though I do think that there's some kind of connection here... in the sense of somebody being susceptible to belief in an overpowering deity not having much of a problem of believing in something illogical.]
Edit: DAMN, forgot to include "I ain't afraid of no ghost" in the poll... T.T
Any mod able to do that? Would be highly appreciated instead of "Hell no!".
