My last one was something that could make a decent fanfiction. It was a mashup of Prometheus, Avengers, and Pacific Rim. Basically, it is the future, and anti-gravity vehicles are the norm. The dream starts somewhere far away, where an Architect was revived from deep sleep. He vows to destroy mankind, his creation, because we are not perfect. He says all that telepathically, due to his vocal chords being cut. He calls his fellow architects, and they get together a fleet of spaceships to fly to Earth and destroy it. I am one of the few humans who learn of this first (forgot how), and I learn hat while at a picnic with a larger group of people, in a forest. After seeing the ships approach and leveling the forest, I grab the nearest speeder bike (junk, but operational and defies gravity!) and ride to my home. After I get there, I tell everyone the news (they are my friends in the dream, despite being complete strangers now that I look back). So, from the windows of the apartment, we see the Architect ships (different than the ones from Prometheus) slowly destroy the city. The human race then decides to quickly go through with a defense program. To fight monsters, we will create monsters. Very quickly. But instead of giants robots, we use magical bullshit science to make superheroes out of people. Those superheroes would make a defense team strong enough to defeat all the asshole creator aliens. The plan is successful, and my dream ends with the first batch of superheroes testing their new powers before going to fight the Architects. I also remember there being one lizard girl testing her freeze powers and looking happy after seeing they worked.
Anything you seen in your sleep worthy of talking about?
