After her first adventures in the human universe, Twilight gets a strange urge to explore other universes. But she isn't prepared the Mental version of her world, her friends, and herself she finds. Especially when that version of her tries to still her life and leave her in her's.

Also,Spike ends up going through his own thing on the side while trying to help with this whole thing.

This is a crossover with The Mentally Advanced Series. And it takes place some time in season four of canon.

Also, one of the first stories in my "Convergence Verse". Though that fact will not be all too relevant within this story.
