A really big fantasy of mine would be a world of madness. Trees eating people. Fishes gained legs and start killing. Gravity inverts once in a while. Rains blood. Deformed creatures at each corner, walls moving and crushing others, solidified clouds falling, Darkness in the day and light on the night monsters of obscene essence would walk the earth love craftian beeings. Fear installed in everyone. No one would be able to say they are sane. Death and screams blood and tears fire and destruction. And then after years of madness silence would come. The world would go mute. Only the ashes and the sound of the wind followed by the occasional screams of pain and anguish of the deformed beeings would remain along with only a few self entitled humans most of them with no sanity anymore.
