Use the story description to answer the question.

A story begins with a character trying to make a major life decision. The character goes
to sleep, and the next day the storyline splits in two. One thread of scenes follows the
character showing their life if they had decided the big choice one way. The other follows
the character showing their life if they had decided the big choice another way. Both
paths involve unexpected downsides and upsides. Near the end of the story, the
character hits their head in both storylines. For a moment, the character fully understands
both realities and must choose which reality to return to.
