Started my day with a bang: what woke me was a dream about
having to dispose of a hand grenade in a hurry, from inside a
house with a floor plan like mine but everything else about it
looking like it was from around 120 years
later[*].
I woke up shortly after the very expensive explosion, while
dream-me was trying to figure out whether I had made the right
decision. (When the thought exercise expanded to, "was my
escaping injury at that distance plausible in real life," that
woke me up.) The earlier parts of the dream had already started
to fade -- enough so that I remember somebody handing me the
grenade with a panicked look on his face, but I don't remember
how there happened to be a grenade in the house in the first
place, how it got activated, or whose house it was.
But the vivid image of many, many square meters of thick glass
crashing down, and steel parts of the building facade bending
inward ... remains vivid. Weird way to start my day.
(BTW, waking up after far too little seep because a dream got
weird and I started trying to figure out the logic of it while I
was still dreaming, happens to me a lot. But almost
always without any explosions.)
[*] That is to say that it looked like a late XXth
Century design.
