Happy Halloween! It's the best time of year for Spiritually Incorrect since we love to cover topics ranging from the bizarre to the paranormal.

And this year, we have a special treat for you:

Joining us is the Pulitzer Prize-winning author Deborah Blum to discuss the topic of ghosts and the supposed scientific evidence the top scientists in the world gathered at the dawn of the 20th century. While nearly forgotten today, there was a time when the study of ghosts was a serious academic discipline, and the results they came up with were... astonishing.

If you don't want your beliefs to be challenged, please consider skipping this episode. For the rest of you, buckle up.
