I can't say that I have any paranormal stories myself but I have heard many stories from people (not just on this thread) who have had encounters with ghosts or spirits or whatever you want to call them. I've heard that some people are more able to see or communicate with spirits than others but I don't know if that is true or not.
Hmmmm... I'm at a loss. Heavy drinking would have explained the majority your posts. Must be something else.
