Someone said that these people are lucid dreamers (clearly this is true for the team, not necessarily true for the target, but possible). Their goal is to get mental elements (memories, secrets, etc.) represented in the dream state as real, accessible objects. To me it makes sense that they would want the dreamworld to be mostly normal. It wouldn't do to try to be breaking into a safe to get business secrets if the building suddenly morphs into an elephant and goes crashing into a wall of strawberries or something. They want everything controlled and normal so they can manage the activities in the dream world.
