Completely weird dream with the Aurora Borealis in it

Last night I had a weird dream, first I was in a ski resort, with a massive amount of snow, and a blizzard like conditions, at night as well. At first, I was in some sort of battle, and I was shooting at some people in a coordinated battle from a hotel room. Then it got weirder, as I was walking out of the resort, the sky was clear where I was looking and there was a perfectly green Aurora before me, but suddenly a small orb of green light shot off it, and then exploded with an unearthly sound, and lit up the area as well. In my dream I remember clearly thinking of The day of the Triffids, as that starts with a similar thing.

Anyway I couldn't get to sleep for a while afterwards.
