This was a dream I had a few weeks ago. Pretty much how it happened in the strip, using a machine gun to stop a fall from a very tall building. Watching the character falling and working out a way to survive his predicament was exhilarating. The Doc is of course up to no good with his experiments so the younger character had to run for his life, I laughed when I saw the machine gun emergency cabinet. It makes sense to have them in all millitary bases with sinister going ons. Toilets in dreams are weird and signify a lot of repression. I enjoyed the dream and making the comic strip version of it.
I don't dream all the time, every few months I might have a great dream. A bit like inserting a Dvd or an old VHS tape into a player, sitting back and watch what is going on for the night.
