What are ghosts?

Ghosts are people who have lived in the past, usually long ago. Some of them visit now and then. Others have stayed here because they still have things to do.

Ghosts are natural. We can't imagine a God who'd say, "I'm sorry, but you're dead. You can't visit your family or your favorite places now."

So, ghosts visit where they lived, worked, and played. Sometimes, they let friends and family know that they're watching over them.

Other ghosts are confused. We're not sure why they visit some places.

'Green lady' ghosts of Scotland watch over the houses where they lived, and protect the families that live there. Those ghosts are called 'green ladies' because they usually wear green gowns.

Some ghosts have something to do, or they want to leave a message. Once they do that, they leave and don't return.
