I'm laid up from a sacral injury (okay, okay, a butt muscle injury), but I'm watching the marathon of GH. It had me wondering about their assumptions.
In one episode, Jason sprinkles an attic with flour because apparently they are attracting bugs or hoping to get footprints. Are we hunting ghosts phantom sounds or the invisible man? Another episode, J&G are using the KII to show that the ghost is in the outline of a human being. Are they hunting a ghost or an invisible man?
In the case of a residual haunting, an apparition or shadow shape will look like a human. This is nothing more than an imprint of something that happened in the past, replaying itself for us visually.
But, in the case of ghosts, why are we assuming they still inhabit a body shape? What purpose would that serve? The body is in the ground or cremated and no longer necessary for transportation.
So, I'm just asking, are we chasing spirits or invisible people?
