Replying...
Intro. You crash-land on a strange unknown planet. Your ship is badly damaged but you survive with minor injuries. Fortunately, the planet is habitable. You explore the planet's environment but by all accounts the planet is uninhabited and only local wildlife inhabits the area. You quickly adapt to your solitary existence, waiting for your eventual rescue. That's why you're greatly surprised when one morning you discover there's another person on your ship. You wonder if she's just an illusion of your own mind.
