Solipsism is a My Little Pony: Friendship Is Magic fanfic created by Shadowed Rainbow. It follows the story of Twilight coming to realize that the world she knew isn't as she thought it wasand she is definitely not who she thought she had been her whole life.
For the wiki's notes on the concept, see Solipsism.
Solipsism provides examples of the following tropes:
- All Just a Dream: What the world as Twilight knew appears to be when Twilight wakes up.
- Alternate Universe
- Enemy Within: It's implied in Chapter 2 that Asteria might be this for Twilight.
- I Know Your True Name: Celestia tries to use said "true name" as a trigger for Twilight/Asteria to wake up. Twilight initially doesn't believe it until her entire world starts breaking down.
- Tomato in the Mirror: Twilight has this realization when she wakes from her life dream and realizes that not only is her name not really Twilight, but Asteria is a draconequus.
