Care to share random ghost stories?

I’m in the mood for ghost stories today, so can anyone tell me a ghost story? Haunted buildings, strange phenomenons, ghost vehicles, true ghost stories… anything!

Note: you must not just post a link to the stories and just ask me to go there and read. I want to hear stories right here. If the story is just too long to post, you can post the link and write a brief (but informative) summary below.

Turn off the light, put on candles, and let the ghost party begin!
