this came up lately in a conversation, and it is a point of contention. i said to someone that i wanted to see a ghost, because it would be a cool experience, i would be able to say I saw one, and it would defeat a lot of pragmatic theories. said person replied with "well what if they kill you?" which seemed outrageous, ghosts can't kill people. but after asking a few other people, it seems they thought the same way, that a ghost could indeed kill you. i still contend that they can't.
what do you think, could a ghost kill someone?
