My attempts remaining: 0

Lore:
Princess Luna failed to secure nightmare of Windstar's dreamland——everything is getting worse as they are pushing forward, with constant size-changing objects, unstable gravity, and abnormal rooms.(seen in the picture above)
Just before the Nightmare could shallow everyone inside the dream, Windstar accidently entered a place which allows him to enter other ponies' dreams, while Luna was forced out of the place due to losing signals of Nightmares.
Ultimately, Windstar gained a different way of cure......against nightmare.

It's my attempt to design a crossover between Superliminal x My Little Pony.

Perception is never been reality.
