What Are Ghosts? – Greg & Woody Want to Know

In the studio this Halloween morning we were wondering what ghosts are -- or rather what YOU think ghosts are.

Some people say they're friendly, some say they're Satan's minions. Are they normal people who haven't "passed on" or are they non-human ghouls? If a house or hotel is haunted, should you go explore and make friends, or stay away? Does your religion have a good explanation for ghosts?

Have you ever heard a believable scientific explanation? Any psychiatrists out there think seeing them is a sign of mental illness?

What do YOU think?
