Parallel Reality

Craft a tale where the protagonist wakes up in a parallel universe.

This parallel universe could be a stark contrast to the known reality, or subtly different in unsettling ways. The crux lies in exploring the protagonist’s reaction to this ‘new’ world, and how they try to fit in or get back home. What rules govern this new world? How would their life experiences or values affect their interactions with this new reality? This prompt could lead to an exciting exploration of unfamiliar territories, realities, challenges, and moral dilemmas.
