Holy moly this thread has gotten scary! I definitely need more cigarettes to compensate!
Fortunately, our house isn't haunted.
A friend of mine seems to think he's seen some mysterious orbs in his room at night. However, he has a wide legal pharmacy and possibly some 'herbal medicine' on the side, so I'm not sure how much stock I put in his stories. I also believe he gets that sleep paralysis thing, from what he has described, so he may just dream it.
What makes me curious about ghosts is wondering why some get "left behind" in places, and why others don't. Our house is 50+ years old, that's plenty of time for someone to have died. A baby died next door a couple years ago, and as far as I know my neighbors don't complain of ghosts in there now.
Another friend says his old best friend comes to visit him occasionally, leaves beer cans out and such. It doesn't bother them, and probably wouldn't bother me, but just curious about why? Obviously he seems to just visit an old pal, my dog just wanted me to know she was ok, so why are some ghosts "scary"? Why do some people die and their ghost never makes an appearance? There's just so much we don't, can't understand.
