The view from hell. A world representing the exact opposite of what one may view as real or true, turned on its head. The exact opposite of this world. It's like bizzaro world in Supermans Universe.

I also see feminine energy, as a upright pyramid represents masculine.

Negative emotions. As a pyramid capstone represents a master, upside down it would be worse than a slave. Like infinity below zero. Right side up would be infinity above zero.
