Do you have any ghostly encounters? Will you tell us about them? I want only first-hand ghost stories, stuff you personally experienced, not a tale handed down from your grandfather or your mother-in-law (even though those may be cool). Also, feel free to do your best at explaining it - e.g., "But then, I was looking through a pane of glass, so I suppose it could have been a reflection..." - just to make this as scientific as possible.
Banshees, poltergeist, telekinesis, and other strange earthly phenomena are fair game, too; it doesn't have to be an actual visible "ghost."
As to whether I believe in ghosts: my answer basically is that I haven't ever seen one, but some part of my mind thinks they're possible. Or, rather, hopes they're possible, because it would suggest life after death and all kinds of interesting physics-related things.
Let's have 'em!
