Nightmare Fuel Episodes are Magic

Friendship is Magic did a good job of Making Nightmare Fuel episodes. Each of the Mane 6 gets an infamous episode where they went crazy.

I found out Twilight Sparkle was suffering from Panic Attacks/Anxiety/Freaking Out/Autism Meltdowns but holy crap that episode is screwed up.

You hear Twilight Sparkle causes a problem and watch the episode:

If Lesson Zero was Planned out differently or did not exists. Would have not spawned Crazy Twilight Sparkle, etc.
