You know I used to know a guy that'd do that. "DEEP SEE", he called it. In call caps, too. Weird right?
About 10 years back, during the enlist, he got stripped down to his spine. Got lot of high order rec and sec burned into him. Pretty intense shit. After the armistice, Sôl Corps decided they didn't want anyone using tech that would make them liable, so they broke into his cube one night and force fed him a datablind enzyme. Knocked out the tech and about a quarter of his braincells. He was in a pretty bad way after that. Only way he could make money was odd jobs with the bits that still worked. Last I heard he was with some private spook group. They cart him around for a day in a nine eye helmet. Make sure he gets everything. Then he drinks till he's nearly dead and wraps himself in blankets and rags till his brain is burning. Apparently it knocks enough of the enzyme out of his tech that he can dream with it. He gets these visions. Sometimes they mean something, sometimes they don't. They always listen to him though. Heard they didn't once. The VIP, some magistrate's son, got an lithium beam through him. They listen now.
