Do you believe in ghosts?

Ah, ghosts, interesting one. Well, there's some great theories about ghosts. I'm prepared to believe in ghosts, I've got no reason not to.

For example there's some theories that there's a lot of iron content in bricks in houses, where they think there's a possibility where you can effectively have a holographic recording of a person, which in certain circumstances can be projected. i.e. you effectively get this wispy, ghosty character.

And arguably, what is time, and life and just because they're a recording doesn't mean they don't have some sort of context and life about them, maybe.
