The sky looks amazing in dreams, and is starting to become a dream sign of mine.

Last night, the sky was a great, dark, purple-blue color, and the clouds were giant and dark. They formed a sort of blunt claw shape, that had a giant chair in the gap. Later on, the clouds formed a giant blanket that looked like wool, and I was pulling it across the sky. When I made the blanket of clouds dissipate, there was a ring of clouds in a bright blue sky. They were swirling, until they shot towards the center and exploded into tons of scattering clouds.

Sometimes, the sky has a very beautiful Aurora Borealis type effect, a giant moon or sun, etc. It's always beautiful, however, and is a great dream sign for me. You guys should try it.
