Yes, I do.

Ralph and I dance at a local studio that has at least two ghosts. One we believe is the mother of the studio owner. I neer met her before she died, but many who knew her have felt her presence inthe studio.

The second we are unsure who it is. We host a haunted house in the studio basement each year, and there is a ghost that hangs out in our maze. Many of us (myself included) have felt this ghost there. I am "back guide" that follows behind the group, does lighting, and makes sure the group stays together. Many times I have been sure someone was still in a particular turn in the maze, only to turn on the light and no one is there. Several others have felt this presence, without having heard stories that it existed.
