Little Green Men

In Harry's head was a picture of the alien, set against an empty black space. It was almost a cartoon picture. On an grey archetypal lunar landscape, shadowed and pitted with craters, and beneath a bejewelled black velvet sky, Harry's mind moulded the alien into a human form.
It was hard not to see the alien as a little green man, fresh out of some 1950's B movie, a death ray firing occasionally from its third eye... but Harry forced himself to remember the weird and wonderful colours he'd seen and slowly, in his mind, the alien took human shape.
