Dreamscape Tales: Wings

When Mira falls asleep, she enters a world unlike her own. She can't seem to awaken, and needs to find out why. Soon meeting many friends and shady characters, she sets off for a way to wake herself from her adventure-filled dream. She's told by a strange man to "Look for the Wings which will guide you home," and so she wonders what all of this could mean.

What's a Traveler? What was she? And why was she here to begin with?
