I initially started my dreams.txt in order to collect a pool of randomness / creativity which I would never be able to come up with in a state of wake. I wanted to collect and then mix it to a story like Walter Moers (e.g. "A Wild Ride Through the Night") wrote.
Unfortunately I never actually processed any of my dreams. But I sometimes read them out of nostalgia.
Just now I proofread a random dream from almost exactly two years ago (2014-07-14) which contained a dreamlike weapon design which I think would actually work and impress me in some crazy space Anime like Diebuster:
I am in some kind of parallel world where the continents are still one pangea. The difference is, that humans much earlier got the idea to use a hammer.
[many things happen]
For some reason they anyway begin to chase me and my friend from school back then, but without weapons. I ask them why they don't have pistols or not even laser guns. At mentioningin the latter one of our pursuers jumps up bringing forth a pumpgun which I gather to be a laser pumpgun looking very similar to the dubstep gun in Saints Row 4. Which means at the activation of it several small black holes open up and red laser beams are flying about around them in "nonlinear" trajectories.

I guess the creativity is not that high. Save for the black holes opening up the laser like beams are there too, I didn't remember that in a wake state before looking it up.
See also the attached animation made with Synfigstudio. If the user interface would be at least a tad shitty in synfig (GTK3) and if it hadn't crashed almost 6 times for this animation I would even be able to use what I learned for this first animation for my sidejob.
