Walking westward on Prince St. between Mulberry and Mott Streets, I heard a woman's voice in my head whispering, "Who's there? Who's there?" Not like I "heard" a woman's voice like when I wear flared jeans with skinny shoes and I "hear" a woman's voice in my head say, "Wait, you've got to be kidding?" but like an actual woman's voice in my head. This usually means I've had a psychotic break.
But! Then I noticed that, above a billboard for some A&E show called Paranormal State were some speakers that looked like hypersonic sound beams, a device which uses your skull as a speaker—that is, it transmits soundwaves that resonate against whatever surface they hit.
So when they hit your head, it sounds like the call is coming from the inside the brain-house.
The billboard says 73% of Americans believe and I'm assuming that that means 73% of Americans believe in ghosts. So if that's true, why try to convert the skeptical/not crazy 27% by beaming voices into their heads? That's just greedy. Also it leads to a lingering sense of serious mental violation. How soon will it be until in addition to the Do Not Call list, we'll have a Do Not Beam Commercial Messages Into My Head list?
