Space invaders, dooms-day and the galaxy's evil empire descending

I was sitting in the living-room just now, looking at a research-show at the BBC. And suddenly I heard this huge low-freequent noise coming from above my head, like the roof was shaking! Like "wrrroooossjiihhhrrmmm....." And suddenly the windows went dark! Outside it's bright snow and sunshine behind big white clouds. You can probably imagine that I got scared there for a milli-second as the living-room went into gloom in the bright of the day, the low growl from the roof increased and the house was shaking! I had no time to reflect on what was going on as I noticed some horizontal glitches passing by in rapid speed inside the darkness outside the window. It gave the impression of thick and big blankets of clay crashing through the air to surround the foundations our house! After the initial fraction of a second with a light freak-out and combating of short-cutting of the brain to evaluate plausible escape-routes, I realized I was back in Norway again in the mid-winter. -as I haven't been for quite a few years. It was just last weeks snow-fall avalanching off the roof due to the recent mild tweak in the weather. Quite normal, and very entertaining 20 years ago! Brain-functions back to normal.
