Horse with No Name

A man and women meet in an arid endless desert world. They do not know how they got there or who they are. Every Night a repetitive nightmare makes their body squirm and doesn't let them sleep, but they have found a way to make it stop. Each night they take turns of waking each other up when the nightmares start. As they get more nights of sleep, visionary dreams start to appear, suggesting where they came from and who they are.
