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 was-and 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.
