Zzzap sees ghosts

“Okay,” he said, “you know I don’t really “see” anymore, right? Not when I’m like this, at least. Not the way you do.”
“I think so, yeah.”
The wraith nodded. “I take in a lot of material from across the spectrum and my mind’s sort of figured out how to process it all as visual information. Visible light, infrared, ultraviolet, radio, television, microwaves, gamma rays … I see all of it.”
“Right.”
“Okay. Well, see, sometimes, all these things I can see come together in certain ways—certain alignments, you could say—and I can see even more.”
St. George crossed his arms. “More how?”
“Like a lot more. About a year ago I realized I can see stuff no one else can. Not with any equipment or lenses or anything, because no one’s ever been able to look at the world the way I do.”
“Barry, what are you getting at?”
The wraith paced in the air for a few more moments. He made a buzzing noise like a sigh. Then he turned to face St. George.
I see dead people.”
