I'm of the personal belief that one Ghosts are there and some people are more sensative and receptive
Or simple weak or one starving for attention.
They do exist. In religions we have another creatures "Jen" on Earth and we have no idea where they are and how they look.
I know what a Jin is religiously speaking and its not a ghost. Ghosts are things you can see,the one who can posses you,spirits of the troubled dead like the andrea says in the post below.
So even religiously speaking ghosts do not exist.
In new Jersey here there are many haunted areas especially where I live because the battle of Monmouth was fought here. Many people have seen a ghost in my restaraunt. People have even experienced stuff in my house. I have experienced it in Philadelphia and Virginia.
Jeez, like i was saying the shit that i have done in my time. You won't believe the haunted places me and my friends have been to and the awesome parties we had there,the offensive things we did there (and i am not talkin going all punk and shouting "fuck you ghost come and get me" shit)...ive been to exorcisms and i have seen parents drag their 6 year old sons and daughters drag their schizophrenic or straight up mentally ill children out of the hospital and straight to a priest.
China is BIG and there are places of war and genocide in almost every city,there are huge abandoned places of disgusting crimes and graveyards reserved for only murders and rapists. Ive been to all of them and we often ended up drinking and firing a grill.
Tell me in my most drunk state i never saw a ghost,so there is no way i will encounter one sober,because they dont exist.
