Well, the thing is, I kinda belive in some of those things, yes, as I've seen two things who made me belive it. One of them I cannot share with you because I've promised a friend I'd never, ever tell anyone about it, but belive me, after I've heard that one, I started to belive there IS some sort of ghost or spirit thing going on.
The second one happened when I was about 11 or 12, I had this 486 computer with a creative labs soundcard (neat stuff back then in 1993, 1994), and it had those awful white soundspeakers, well, sometimes I used to listen to laughs and weird voices speaking in giberish. I'd get so scared I'd start to cry and turn off my computer right away, and lock the soundspeakers on the closet, or sometimes just hidden then behind the computer - it was like Haley Jley Osment (or whatever it's spelled) on Sixth Sense. It happened to me about 5 times, sometimes it was a spooky laugh, sometimes someone speaking stuff I couldn't understand, always a male voice. BUT I've always suspected I was getting some sort of a radio frequency or something of the sort: it never happened if the speakers were turned off, and it sounded kinda radio-like, sounded like the pilots on the Yavin battle, but I little bit more clearer. Wait a minute... laughs, giberish talk... I was getting a transmition of ROTJ, that was Jabba!
