I've had 2 Sagan 4 Alpha-related dreams that I can remember off the top of my head. Both involved saucebacks.

In the first, the dream itself wasn't really what was interesting. I was just having a dream where I was a frosty sauceback, probably frolicking or something. However, I needed to go to the bathroom, so I got up and started to sleepwalk towards the bathroom.
Emphasis on sleepwalk. I was still dreaming, and I still thought I was a sauceback. I remember being able to see, my eyes were open, but saucebacks can't see--they use echolocation--so I ignored my eyesight and tried to navigate via echolocation.
Of course, I walked straight into a wall and immediately woke up.

The second that I can remember was last night. I was visiting my grandparents I think, since it seemed to be their house, but it was right next to Niagara Falls for some reason. At some point, a sauceback--some kind of descendant of Brighteyes which was about as long as I am tall--got loose inside the house. At some point we lost track of it and assumed it got out the same way it came in. Then there was some kind of monologue about how Niagara Falls works, which I'm 99% sure was false.
Turns out the sauceback was still in the house, it had just gotten lost and tangled in some clothes inside my sister's messy, messy room. It took 2 people to successfully catch it and put it outside.
