Dream

Both last night and the night before were non-melatonin dreams. 

Last night I dreamed that there was an extraterrestrial existential threat to the earth, and we (the collective dream we, I don't recall specific characters) needed to combat it by using super non user friendly technology. It felt very Enders Game in that regard. 

An alarm would sound, we'd scramble to get our equipment set up and struggle to operate it. I recall my father being visited, but he wasn't disabled and he was smoking a cigarette. He gave us advice on how to use a specific aspect of the technology, or gave us a new piece of it or something. I also remember my mother having been present but I do not recall the context. 

I also recall that there was a large cylindrical hole in the ground, studded with dwellings on the way down. People huddled in these for safety from the aerial attacks. The whole dream had a very hurry up and wait element to it.
