I have a lot of artifacts - books on witchcrafts and talismans. I have a big, big collection of original occult books from the 1800s and 1700s, and some of the oldest books on apparitions and vampires. All original printings. It's not that I'm a crazy believer, I just find it to be amazing research material.
Imagination has brought mankind through the dark ages to its present state of civilization. Imagination led Columbus to discover America. Imagination led Franklin to discover electricity.
