A little help with my Mars dream

I've been having a recurring dream involving Mars lately.

First off it seems as i'm one of the astronauts on the first manned mission to Mars. About twelve of us arrive on the planet and it's just how it should be, uninhabitable. This is where it seems to get weird.

I must have went into some kind of coma for some reason because i remember getting there and checking things out but then i wake up and everythings different.

When i come to there is some sort of colony on the planet with green grass growing and small trees climbing into the sky. It's like a little suburb on Mars. It seems as though we made it possible to live and dream on the planet and there are about 500 people now living there.

If anyone has any idea why i continue to have this dream please let me know. It's happened about 5 times now and trying to have it interpreted in one of those dream websites just doesn't get me anywhere.
