The so-called "cemetery" has no walls, no fences, and nothing to protect it. It stands completely open, like an invitation to danger. Because of this, any creature, whether a wild beast or a nightmare monster from the Dream Layer, can easily enter. Once inside, they can wreck the place, absorbing the lost souls and corrupting them to their ugly counterparts.
Using a simple illusion, the Dream Layer can easily trick travelers. Someone walking here might see a safe haven, but the layer shifts things just a little, like a gentle push to the right. Before the traveler understands what happened, they already find themselves standing in the middle of the twisted, broken graveyard.
