My wife and I were helping a friend with a production she was putting on at Piper's Opera House in Virginia City, Nevada. Piper's has been around since the Comstock days, c. 1860, and it's currently being renovated to it's past glory.
Anyway, my wife and I were backstage in a wing helping setup props for the show when my wife looked up onto a loft and said, "hey, where did that come from?". I looked up and didn't see anything and asked her what she saw. She said, "that headless mannequin--it wasn't there before". I didn't see anything and went about my business.
Later, my wife was recounting the tale to some other people there that night and supposedly that "mannequin" was one of the ghosts that haunts the old Opera House.
Believe it...Or Not!!
Everybody is up for a good ghost story, anytime.
While staying in a cabin in Michigan, I neglected to empty an overfull garbage can from the kitchen.
When my wife arose that night at 3 AM, she screamed. The garbage can had been moved to block entry through the bathroom door.
No one could have come into the cabin that night and done that. I stared at the ceiling till dawn.
Not all spirits have physical bodies.
