Swapdream (also known as SwapDreamtale) is a derivative AU of Dreamtale, created by the Tumblr user Song_A. This alternate universe closely resembles the original, with a few notable differences. In this version, Dream finds himself in a setting where he consumes a staggering 999 apples. The narrative revolves around Nightmare's quest to eliminate Dream in order to prevent his deranged brother from seizing control of the world.
