A surprising number of people believe in ghosts. A 2014 UK survey found that 52 percent of participants believed in the supernatural. A 2015 survey by Chapman University found that more than 40 percent of Americans believe places can be haunted by spirits.

1. Electromagnetic Fields
4. Carbon Monoxide Poisoning
5. Someone Else Said It Was Real
6. We Want to Believe
