First things first

Then again, there's my wife who is an atheist but believes in ghosts.

But does she believes that the things referred to as Ghosts used to be living, breathing humans?

There's something going on with the ghost phenomena. But to jump to the conclusion that they are the spirits of formerly alive people is a jump in logic for me. And one not based on any evidence.

Yeah, but there are some odd things going on, on this planet.
