When I was a kid, I used to listen to a radio show called Mystery Theater Radio on a transistor radio at night. It was a show that had weekly episodes about mysteries, hauntings, and other macab subjects. There is now a site that lists the over 1300 radio shows that were made for Mystery Theater Radio. Some of them can be scary, so kids ask your parents before you give them a listen. Here is the link:
