Weird el espacio Dream.....

almost as akward as some of my dreams

Dreams can mean something, o nothing at all. It depends on the way tu look at them. I can see meanings in most dreams. Here is my interpertation of why tu may have had a dream like this:
About the desert: tu may feel alone at the school tu attend and often lost. Think about someone riding camello back searching for water, desperately dehydrated. Now think of yourself as the camel, lugging a heavy load, (Your book bag), through the halls trying to find water, representing your classroom.
About the human aliens: This may represent the uniqueness in people. They look the same on the outside, but have 'alien' personalities..
The book: Representing time. It goes por quickly. The book becoming unavailable segundos later may be telling tu that tu must reach for what tu want within a reasonable amount of time. For instance, tu want to audition for a play because theathre intrests you. tu need to find the fecha for auditions but know its not tomorrow so tu procrastinate until the oppurtunity is gone.

We all have strange dreams but they often can say something =] Though they won't always mean a thing at all.. I once had a dream that a giant salamandra was trying to take over the world. I had to save the día so I threw a cow at it. Sorry this is long
