existencia de los fantasmas

“Ghosts are beings that live in the spirit world. They’re impressions left by a personality at the moment of death. They aren’t like people, or sentient spirits like
you. They don’t change, they don’t grow—they’re just there, experiencing whatever it is they were feeling when they died. Like poor Agatha Hagglethorn. She was loopy.”
The skull turned its eye sockets away from me and said nothing.
“So, they’re spirit-beings. Usually, they aren’t visible, but they can make a body out of ectoplasm and manifest in the real world when they want to, if they’re strong enough.
And sometimes, they can just barely have any physical existence at all—just kind of exist as a cold spot, or a breath of wind, or maybe a sound. Right?”
