By killing the host or being given control of the nightmare. One is given the right to control significant space and shape it as they please.

But he hadn't done that. This delusion was his own attempt at such an enterprise. He copied an island, later he populated said Ark with his own creations. Another island was place close by. An massive underground cavern was placed directly under it. These trials here were of no importance. Just humor and fun for himself. As they are in his ps4 they were now in this nightmare. His personal prison, a dessert with only one oasis, here thoughs he deemed dangerous or invaders would be sent so they may not interrupt his experiments. But this was temporarily it real purpose would be to train battlemages. Mages without the ability to cast spells. They would be trap and under constant siege, every morning at sunrise different type of horror would feast on them. None may pass the ghost fence. Once one entered they would experience hell.

But back to the ark, a land empty of animals couldn't be so. He then scrutinized his work, so far he'd had stole other creations. But these where just cosmetic. They would become something new, his creation. All without having to spend all day designating there looks and appeal. He cared not for such thing. The fridge north was populated with owl like creatures. The males form resembles humans covered in feathers with large wings on there back. While the head was that of an owl. The females were much bigger in comparison. Instead of appearing human like, it was much easier to discribe a bear. Though they too were covered in feather and poofy like there counter parts. They didn't have wings on there back. There wings were there arms, though this means they lacked fingers. They could only fly short distances. These wise creature would teach poor souls the basics. They were task with teaching the technology of primitive weapons, tools and armors. Before forcing them on rafts to the dangers islands.

Then he moved to the marshes, jungles, caverns and desserts. Here he dropped lizard men into his nightmare. The males were hulking behemoths, with crocodiles head and colors. While the women where much smaller and slender in stature. He'd give them an edge over his other creations. There egg brothern the raptors would flock to them. Together they shall hunt down there competitors. After there placement setting, he then went to work. The games he had stolen these creatures from provided much but it still was lacking here and there. For starters there were game elments that need to be desolved. About half way threw his burden was becoming hard to bare. His head acked like never before, so he spread the burden to some of his creations. Connected there minds to a specific section of the library. This would help stability of the island by forcing them to take an active role in habitat management and nightmare hosting for there existences was at stake too. The whole nightmare was placed in an array that would connect to the library and a board. Its job was to steal information that would help with creating a more realistic islands. The more people that visit the harder it would be to discover any flaws. Next was the scripting and the board owner. Lastly came the food source, Gorillas. He would move troops of gorillas on beaches ajacent to the jungles, but not now. Each inhabitants was created from wisp. When he deem it so they would wake. With false memories and animal instincts. They would behave as he had demanded them. But now he had to take his time creating memories for all of them. He had to teach them the law of the jungle. What to eat, how to use there bodies. While giving some of them history and culture. Lastly the more intelligent need there own personality. This took a years of nights. But when it was finished a nightmare was born and what a nightmare it would become to the poor invited guess who would spend there nights here. But first the test subjects it couldn't be so horrible or it would defeat its purpose and who knows what if there were problems he didn't think of. But what ever the results he would enjoy himself.
