Learn to control your dreams anon, it takes some practice at first, but then you begin to do it every night. I am the ones giving people in my dreams nightmares. I remember once, i was flying over this foresty land with villages below in this kind of airship. I suited up and descended down, we were invading this place, the ship was raining fire and doom and i was just going around wrecking havoc.
I've had dreams where i have to explore the creepiest places i make in my mind, an old house for instance. Walk inside, there are monsters there, but i cannot die, so i repeat until i manage to kill them all and perfect the "level."
