In: Alien invasion

Had a dream that me and my mom went to movies. When I left to get popcorn, a fat guy was sitting next to her and being aggressive. I called security, but the fatso killed both security guards and started behaving like a terrorist. It turned out it was an alien invasion. My mom was taken away by aliens as all parents, and all children of the Earth taken underground. When I, another child, emerged, I saw the Earth has changed into a red, smoky, volcanic looking planet, with a clear, dark ocean. The water was warm so I went for a swim. An alien told me it takes "100 laps" for my mother to swim back to me from another side of the ocean. As I tried to escape under a plot, I was trapped and put into a plastic bag(like a fish). Then, I see myself as a cleaning lady, cleaning up the planet from newspapers and other clutter and freeing my other self from the bag. I remember saying, Mom please swim back to me.
Now, this dream is easily explained. I subconsciously want for my mom to come to me across the ocean, but she is with a big fat man right now, whom I see as an invador. Then, I myself feel trapped by circumstances - the plastic bag.

In onto Out, the meaningful dream

I saw a fog, shaped like birds all over the sky, and thinking it was the end of the world. Because I am sick today, and its really IS like the end of the world, in some sense, you can say that this wild dream can be totally explained. The viral infection takes the image of birds(bird flu carrier). I also run and collect colorful crayons from the floor, which makes no sense so far, but maybe... a sign of some creative self expression?
