Archaic KJV Word
Dream
Modern equivalent: subconscious imagery
What Was Lost
The divine sender. In scripture, certain dreams were not produced by the sleeper's brain but sent by God -- they carried information the dreamer could not have known. Joseph's dreams predicted the future. Daniel's dreams revealed empires. These were not subconscious processing but divine broadcasts received during sleep.
