While in the Dream World characters can use Mind Crafting. Through this characters can interact with objects in the real world. Real world objects seem to glow red, and zombies and weak-minded humans are able to be killed there (though the likes of Bernie and Jess are shown to be protected).
Manipulated by Andrius, Joe was shown on camera entering the Supermarket Base via the lift and breaking the door to Andrius' cell, despite Joe believing himself only to have been interacting with similar objects in the Dream World. Two soldiers were also killed by Joe via the Dream World. Though Andrius claimed to have created them via mind-crafting, this was a lie as the two soldiers were later discovered dead.
