How's This Work?

Another question, brought up after reading this:

The poll shows 32% of all adults say they believe that "ghosts/spirits of dead people can come back," while 48% do not, and 19% are unsure.

Even more Americans believe that houses can be haunted, with 37% holding that position, 46% saying no, and 16% not sure.

Uh... more people believe in hauntings than in ghosts. What's haunting these houses, if not ghosts? And don't try "spirits," either. That's still under the "ghost deal."

Which reminds me, Eric...
