Jake was able to make a Dream Ghost Dirk, and when he went full power after Aranea DGD became real. Before that Terezi(Seer of Mind, keep that in Mind(HA! Puns)) could see DGD when no one else could. Now stay with me. When on the meteor, Terezi told Tavros not to believe anyone that says Rufio isn't real. Could all Pages have the ability to make mind projections. And if so, could a Page of Mind make an army by just thinking hard enough(since these projections are more of a mind thing)
