Well.. Fuck. I can't find any images that would reflect any of this, so remind me to either draw or paint this shit someday.
Whenever I am calm and tranquil, my mind is a slowly consuming vortex of neon energy, with islands of black obsidian floating in a lazy orbit. Shards of the dark rocks fall off, and then drift into the efferescent void. Every now and then, a stone spire will light up with the sigils of creation, and emit a bright blue pulse that shakes the island chains.
As my mood lifts into a happy state, the islands settle around the vortex in a long and rolling plain. Great tall grass sprouts from beneath the battered rocks, and the energetic anomaly reduces to a pulsing storm. The plains begin to dampen with multicolored rain, as brightly lit seeds fall from the sky like meteors. Ephemeral stallions of smoky blues and teals roam across this land, bringing joy and creation.
Should I ever get angry, the entire chain of islands explode one by one into a flaky dust, as they reveal hideous structures of bone and flesh that weep and ooze pus out of every crack and crevice. Plants of barbed wire and fangs pierce the tissue of the landscape, and the sky darkens into a fiery orange. The land itself begins to spew putrid creatures that curse their birthing, and fight eachother as they try to end their own lives as quickly as they began. The plants consume and writhe, cutting and searing whatever they touch, and the air itself thickens into a searing pressure of hate.
If I get sad, everything wipes into a grayish haze, as lights, and even sound is devoured by the agonizing mist. The ground beneath is covered with freezing patterns of either ash, snow, or rain. Dark forests of wild shadows sprout, and tower into the tops of the haze, as beasts with golden eyes, made of nothing luber about just out of sight. Everything within sight becomes a murky shade in the distance, and the closer you get, the less real it becomes. Everything becomes etched and inked, as if a pen scratched out your vision.
Those are my mental landscapes... I guess.
