Dream and Nico
"It depends on the person and what's going on in their lives. Dreams are part of the subconscious after all." It was why when some people went through something traumatic, they tended to have nightmares about it. If they were in love, they dreamt of that person, and so on.
"I wouldn't call it fun, but it's my job and I do it." He didn't do 'fun'. He was always more businesslike.
