Little Witch Academia - Season 1 Episode 8

After drinking her own ominous energy drink formula, Sucy winds up in a deep sleep with mushrooms growing around her body. Unable to ask for a teacher's help out of fear of expulsion, Akko has Lotte send her into Sucy's dreams so she can find out how to cure her. Enlisting the help of small angel and devil versions of Sucy, Akko encounters several different personality aspects of Sucy in her search for the original, only to get caught up in a judicial purge of Sucy's unneeded emotions. After stopping the execution, Akko rescues a smaller kind-looking Sucy and soon comes across a drive-in cinema showcasing Sucy's memories. Just then, the Sucys that Akko rescued merge together into a bloodythirsty monster that threatens to overtake Sucy's original personality. After rushing to find the original and attempting to wake her up by feeding her antidotes via mouth-to-mouth, Akko wakes up from what was apparently her own dream.
