Alien invasion

Yes, I am quite aware that there are certain reoccurring themes in my dreams.  And aliens seem to be one of them.

So last night, I dreamt that earth was being attacked by aliens.  I looked in the sky and saw a flying saucer that filled most of the sky in front of me.  The unusual thing about this spaceship though was that unlike the flying saucers you typically see in movies, this one was also quite thick (to scale, imagine 6 or 7 CDs stacked together).

Anyway, from the window of this ship, I could see the aliens, and on the ground people were running around in a wild panic.  We all ran into this building just as a beam shot from the sky, directly from the craft.  The last thing I heard was a friend of mine shout "Our race is doomed!" before everything turned white.  And it was at this point that I died.

Or at least, that's what I thought.

I woke up thinking that the dream was over and that earth had been destroyed, but when I went back to sleep, the dream continued and it turns out I had somehow survived the blast in once piece.  Anyway, the aliens had now colonised the planet, and I was talking to a woman who explained that the aliens viewed us humans the same way we view insects and that they thought nothing about wiping us out.  The remaining humans, including myself thought about getting together and forming some kind of resistance.

Later on, I was in a bathroom stall brushing my teeth when a female alien walked in.  She had long, pointy teeth and explained that her race had nerves on their teeth that caused sexual arousal when they were stimulated, which made her interested in my toothbrush.  That's all I remember.
